ABSTRACT
A call centre is of strategic importance to an organisation and therefore needs to be developed
with ergonomics in mind. Call centre managers’ need to be trained in the field of ergonomics, so
that an ergonomic “changeover” takes place to improve the workplace. Call centre agents are the
lifeblood of the call center, and efficient managers need to do everything in their power to
maintain a competitive workforce. The creation of worker friendly environment boosts the morale
of the workforce, thereby reducing turnover and attracting professional agents. The issue of
labour efficiency and productivity need to be addressed with the application of ergonomic
principles which contribute process improvement. The result would be a reduction in absenteeism
and worker's compensation claims as it is approximately ten million per year (www.statsa.org.za).
Musculoskeletal disorders (MSDs) such as carpel tunnel syndrome arise from poor ergonomic
practices. Thus, the focus of this article is to promote the application of ergonomic practices in
the administrative environment with a view of improving worker health and safety while
improving productivity.
Keywords: ergonomics, office, productivity improvement, call centre
INTRODUCTION TO ERGONOMICS
Ergonomics is derived from two Greek words: ergon, meaning work, and nomoi, meaning natural
laws, to create a word that means the science of work and a person’s relationship to that work
(www.system-concepts.com).
The International Ergonomics Association has adopted this technical definition: ergonomics (or
human factors) is the scientific discipline concerned with the understanding of interactions among
humans and other elements of a system, and the profession that applies theory, principles, data
and methods to design in order to optimize human well-being and overall system performance
(Stevenson, 2007).
AIM AND OBJECTIVES
The aim of this article is to provide an overview of ergonomic practices in the administrative call
centre environment and to create an understanding of how simple changes could improve the
health and safety of the workforce while also enhancing productivity in the organisation. The
following objectives will be served by the study:
• Observation of problems relating to ergonomics at workplaces.
• Development of a process improvement framework that would serve as a benchmark for
the application of ergonomics.
METHODOLOGY
The research comprised a qualitative exploratory and descriptive design. The purpose of the
exploration was to report the current phenomenon of ergonomics through systematic observation
(Cooper and Schindler, 2006). Personal interviews, questionnaires and direct observation were
used to gain insight into problems caused by poor ergonomic design. Observation of task
performance was acquired; both to document worker technique and worker interaction with their
workstation as well as to provide examples that can be used during training (if training is pursued
as an intervention). Operators were spoken to, to obtain a general consensus on the problems
experienced during the performance of the job.
LITERATURE REVIEW
Branton in 1993 has moved away from the contemporary views of ergonomics and has
concentrated his efforts on the most important variable, people. He realised that people at work
bring unique characteristics to the system, which no machine would ever hope to match. By
recognising the employees’ sense of flexibility and responsibility at their work, he believes that
people can make the difference. Therefore he created a ‘person centred’ view that would enable
action in the workplace .The researcher is in full support as without people, ergonomics would
not happen, and continuous training is the key factor that South Africa lacks.
Haslegrave in 1990 indicated that ergonomics would improve the variables of safety, quality, and
productivity. In the publication “Work design in practice” a number of case studies by different
authors have been compiled in different industries. The variables covered ranged from ergonomic
planning of industrial plants, problems addressed in the workplace and an ergonomic workplace
design. The case studies outline the reality of situations in industry.
“A guide to the ergonomics of manufacturing” provides an in-depth evaluation of ergonomics and
the way in which it can enhance the variables of productivity, safety and job satisfaction. The
difference is the focus on job satisfaction, which is of prime importance to all human
interventions. Job satisfaction is a major contributor of a motivated workforce, which in turn
improves productivity. Helander in 1995 explains the many ways in which ergonomics can
support and improve human work. It grounds these ideas in real-life situations. This information
is applicable to a variety of industries including its general applicability to the administrative
industry.
The “applied ergonomics handbook” by Galer (1989) has drawn a number of experts from the
field of ergonomics and discussed the variables of design of displays, controls and workplaces,
the layout of workplace and issues in the working environment including climate, noise,
vibration, vision and lighting. The researcher is in agreement with the information, but the
limitation is its application to the administrative environment.
According to Fleming in Allnoch (1997), “improve a worker’s comfort level, and you improve
the company’s productivity level.” Ergonomics is designing things better, or integrating better
work methods, work practices, and equipment to humans. He feels that industrial engineers have
spent a lot of time on materials, on the process, and on the machinery side, but they’ve not
thought enough about the human and how the human functions. The researcher is in total
agreement with this situation due to his exposure in the field of ergonomics.
The literature review evaluates ergonomics and its application to industry in general. It covers a
broad spectrum of variables that concentrate on a more industrialised environment. The
researcher would like to focus on the administrative environment.
According to Alexander (1985) typical losses from the failure to apply constructive ergonomics
include:
• Lower production output
• Increased lost time
• Higher medical and material costs
• Increased absenteeism
• Low-quality work
• Injuries, strains, fatigue
• Increased incidence of accidents and errors
• Increased labour turnover
• Less spare capacity to deal with emergencies
• Reduced productivity
• Reduced competitiveness
Ergonomics will make a difference if implemented constructively. It has to be a team effort by
both management and operatives.
The negative impact of autocratic management
The autocratic style of management is a recipe for under-performance of organisations. South
African managers need to be re-skilled in dealing with people and tap into the potential that
resides in their people. Currently, there is a huge gap in organisations’ values and how they act.
This can be remedied by:
• Reviewing the organisation culture and values; and
• Re-skilling people to enable them to ‘do’ what the culture calls for.
This would result in congruency between values and actions and would in turn encourage
innovation, creativity and risk taking. In essence, how managers deal with their people would
create the environment in which people are able to motivate themselves. This is what South
Africa needs – to work smart, and not hard. The education and training philosophy is important
for the success of ergonomics. Stapelman in 2000 stated the need to apply the “SMART”
philosophy. It entails the following:
S – Specific in terms of focus on a subject
M – Measurable in terms of it being quantifiable
A – Achievable in terms of the standards being attainable
R – Results orientated in terms of something constructive being achieved
T – Time Framed in terms of time limits being stipulated.
The SMART philosophy is extremely important in a changing world of technology.
Why is there an increased interest in ergonomics?
The increasing interest in ergonomics can be attributed to a number of factors. The most obvious
are the rising costs associated with work-related injuries or illnesses. Legal policies and
procedures are being regulated in all industries around the world. There is pressure from labour
unions and insurers which have increased employee awareness. This is focused on an
environment conducive to the task performed and there is mounting evidence that ergonomics
programmes can positively affect quality and productivity. These issues combine to make
ergonomics an important issue. Worker injuries and their subsequent costs, both direct and
indirect, often are the result of some problem with the interface between a worker and a machine
system. As technology improves, it leads to increases in automation, so too have work-related
illnesses increased – witness the tremendous rise in cumulative trauma disorders, the fastest
growing category of workplace trauma in a stressful environment. Causes include poor or
unnatural postures, static postures, excessive force required to perform a task, repeated movement
at high frequency, insufficient recovery time between repeated movements, vibration and cold
temperature (Render and Heizer, 2006).
The ergonomics problem has become so serious that fines are issued to organisations. Direct
medical and compensation costs are being incurred by all stakeholders as a result of poor
ergonomic management which represent a significant loss and could have a detrimental effect on
profits. There are, however, additional losses associated with ergonomically-induced injuries and
illnesses. These are the costs associated with absenteeism, restricted work day cases (workers can
return to work, but not to their regular job), turnover and retraining (Rowan and Wright, 1994).
DESCRIPTION OF THE INDUSTRY
This section presents descriptive statistics from the survey sample. Call centre operations at three
organisations were used. Organisation A is leader in technological innovations in the cell-phone
industry with 150 operators. Organisation B is a state of the art call centre in the banking industry
with 100 operators and organisation C is a call centre in the education environment with 150
operators. To respect the anonymity of the industry, names and other direct identifying
information are not included.
LIMITATIONS OF THE STUDY
A research project generally has limitations. In this case, because of the political nature of
government departments, managers were wary of being interviewed. The primary obstacle
encountered was the reluctance of staff to provide information, weary of being victimised. There
is a focus on the immediate work environment.
SURVEY EVIDENCE THROUGH CASE STUDY APPLICATION
The survey focused on a qualitative approach of gathering information through questions based
on the current experiences of the industry. Information was gathered through, personal
discussions with individuals and direct observation. The results provide questionnaire topics of
the various categories of information gathered from the organisation.

SUMMARY OF SURVEY RESULTS
Summarized results are shown in Table 1. A,B and C are the organisations while Y= Yes
responses and N = no responses. As an example 60 respondents of a sample of 75 mentioned that
they perform other tasks during the call centre operation process, which is equivalent to 80%
(question 1). It can be deduced from table 1 that organization C has a problem with their
ergonomics management and needs to implement ergonomic principles. On evaluation of
organization C, there seems to be a major problem starting with management, motivation levels
and the death of individuals. In the past 5 years, 3 agents lost their lives through suicide due to
high stress levels, approximately 75 agents are on medication and very little seems to be done
about the welfare of the agents. Approximately 50 % of calls are lost in peak periods (registration
period) because only 50 % of staff adhere to ACD (average call duration) time whilst others are
involved with administrative and other activities, sometimes non-productive activities.
Experience shows that 25% of the staff was non-performers and nothing is done about it. If the
calculations are done in performance management and the workload is distributed evenly, the
problem of non-performance could be reduced.
Organisations employ substantial numbers of agents from different population groups that vary in
anthropometry, thus making the adjustment of workstations difficult. The objective of the
programme was to document patterns of musculoskeletal injury or discomfort experienced by the
agents and to begin relating them to the job and workplace elements that might have contributed
to them. During the interviews, the agents related the frequency with which they experienced
muscle or joint pain in each of the 16 areas of their bodies.
Approximately all workers reported that they at least sometimes experienced pain in their upper
back (80%), neck (49%), and right hand (70%). This prevalence of neck, shoulder, and back
discomfort is consistent with results of similar surveys on workers throughout the world.
The data are also comparable to those found in a separate study in which a sample (n=15) agents
rated their comfort levels at four different points of the day. Discomfort tended to increase
throughout the day and by late afternoon 12 out of 15 were reporting some degree of discomfort
in their upper backs, 8 out of 15 were reporting discomfort in their right hands and 5 out of 15
were reporting discomfort in their necks.
Much of the reported discomfort in the back and neck can be attributed to the working posture of
the seated agents. In response to job and workstation characteristics, agents typically adopted a
hunched working posture. Analysis of the postures made of sixty subjects indicated that 40
percent stooped forward (i.e., torso flexion) at least 20 degrees throughout the call duration.
Several workers stated that this posture is necessary to obtain maximum output. Such postures
have been cited as a factor in muscle fatigue, and discomfort (Grandjean, 1982). The tendency of
operators to work in this hunched posture can be attributed to at least three factors, the visual
demands of the work and the geometry of the workstation.
All agents complained of the visual strain of computers that need to be worked on throughout the
day. Agents also complained that when the florescent light goes off, it takes about a month for it
to be replaced.
The tendency of agents to work in the hunched posture also suggested a potential conflict
between workstation geometry and operator dimension. Analyses indicated that the location of
the computer screens and the keyboard were not centralized.
All agents performed their tasks in a seated position but there was a lack of adjustments to enable
agents to adjust their chairs according to the required height of the work station.
Management, with the capability of leading people towards performance improvement, could
improve the morale of people by providing an environment in which work could be done through
an ergonomics improvement plan and effective communication among individuals (Ramdass,
2007).
Call centres demand innovative, cost effective, space saving designs with an emphasis on people
management in a diverse cultural society. The major contributors of health and safety risks are
work-related upper limb disorders such as voice loss, throat infections, stress, a feeling of being
cooped up and a lack of fresh air. To add to the problem, electricity black outs prevent the use of
all electrical appliances such as air-conditioners.
RECOMMENDATION FOR EFFECTIVE CALL CENTRE DESIGN
Due to it being a labour intensive environment the motivation level of the workforce needs to be
high to obtain maximum output – a participative management style that listens to the problems
experienced and a constructive effort of problem resolution. Change is initiated by leadership
with strategic vision for the success of an organisation. The vision and mission comes from the
organisation’s leadership (Stevenson, 2007). Visionary leadership drives the organisation towards
the attainment of organisational objectives through the transfer of decision-making ability to the
workforce. Thus the efficiency in the utilisation of resources is improved through the elimination
of barriers between stakeholders and the creation of trust.
Visionary leaders create and articulate a realistic, credible, and attractive vision of the future that
grows out of and improves upon the present. Visionary leaders have three skills: ability to explain
the vision, ability to express the vision, and ability to extend the vision. The leader needs to be
proactive and use the current threat as an opportunity towards the creation of a competitive
industry. The barriers in communication should be eliminated through the application of
communication skills and the respect for others. The sharing and learning in the workplace
develops an increase in morale and the exposure of employee capabilities (Render and Heizer,
2006).
Leadership has the key to changing the organisation around through the effective implementation
of fundamental methodology that would improve the ergonomics of the call centre industry.
Argenti (2005) mentioned that he “lays the blame for business failure squarely at the feet of the
often autocratic chief executive.” The researcher agrees with Argenti as this is experienced in the
SA clothing industry. He mentions two issues; firstly that the leader does not accept the need to
change the current operation, and secondly, the leader is overambitious and considers that he/she
is flawless.
Carson (1991) mentions that there are “three distinct areas of weakness: leadership, finance and
competitive failings. This is often linked to marketing inadequacies, particularly concerning
developments and improvements at an appropriate time. He also highlights the danger of
overambitious major projects and acquisitions which either cost too much or fails to deliver the
hoped-for synergies.”
Trust is an important ingredient of leadership and some of the aspects that enhance trust in
leadership are the following: (Botha, 2000)
• Trust appears to be a primary attribute associated with leadership.
• Part of the leader’s task has been, and continues to be, working with people to find and
solve problems, but whether leaders gain access to the knowledge and creative thinking
they need to solve problems depends on how much people trust them.
• When followers trust a leader, they are willing to be vulnerable to the leader’s actions.
• Honesty consistently ranks at the top of most people’s list of characteristics they admire
in their leaders.
• In times of change and instability, people turn to personal relationships for guidance, and
the quality of these relationships is largely determined by level of trust.
Thus the researcher would like to stress that without leadership that embraces change and process
improvement initiatives, the organisation would remain stagnant with minimal success rate.
IMPROVEMENT STRATEGIES
It is important to note that although strategies for a congenial work environment are in progress,
certain aspects could be addressed in the short term. It is the shortsightedness of the researcher
that not all aspects were addressed during the study due to time constraints
Comfort
Comfort is imperative in a call centre environment than in a normal office situation. Temperature
needs to be maintained at comfortable levels during the 4 seasons, with a circulation of fresh air
at all times. A great deal of thought needs to be given to the positioning of a call centre in a
building. There is a tendency to place the call centre in the middle of the floor, with no access to
natural lighting or windows. This leads to a feeling of isolation and depression unless care is
taken on lighting and décor. Footrests should be provided to accommodate the different sizes of
people. Footrests add comfort to the agent during the operation. The provision of palm rests for
the workers with wrist/hand complaints – this would enable the operator to perform their tasks
within their workspace with more ease and adds to the comfort of the agent (Alexander and Pulat,
1991).
Temperature, air movement and humidity influence how comfortable an office becomes,
particularly when sedentary tasks are performed. There are considerable differences between
individuals in their preference for thermal comfort and it is unlikely that one temperature will suit
everyone. Some workers may be sensitive to changes in air quality.
Air quality can be affected by activities such as dust from construction work and fumes from
carpet installation. If symptoms relating to skin or eye irritation or breathing difficulties are
noticed that could be associated with such events, the agent should notify the supervisor.
Supervision need to investigate when construction activity (or any other activity that hinders the
well-being of the agent) would be completed (Byrne and Rigby, 2000).Locating workstations so
that the individual is not sitting close to, under, or in front of an air conditioning outlet may
prevent staff being affected by draughts.
Training
Agents need to be trained to properly adjust their chairs and to sit properly -
The chairs that the majority of workers sit in seem to be adequate ergonomically. However, a
good chair set in the wrong position can still cause problems during prolonged sitting. Training
should be provided on how to adjust the chairs, and why. For example, if discomfort develops in
the low back, the seat back may be too high, or if the back of the legs get sore then the seat pan
may be set too high. Proper sitting posture should also be taught (Dillard and Schwager, 1997).
Agents need to be trained to stretch properly, and the provision of stretch breaks is necessary. The
effective implementation of stretch break programmes ranging from voluntary when the worker
feels the need to mandatory five minutes every hour. The stretches need to be appropriate and be
led by properly trained leaders or the individual workers need to receive training (Gryna, 2001).
Medical Management
Implement a medical management program that would include training for the agents and
supervisors so that they can recognize early symptoms of CTD problems, and make sure that
management promotes a policy of early reporting so that CTDs are prevented. This type of
program would need to be corporate-wide to be effective. Experience indicates that an effective
medical management program can prevent minor aches and pains from becoming lost workday
incidents. All the biomechanical modifications could be made possible and still have a large
number of lost days if early reporting and aggressive pursuit of treatment are not part of corporate
policy (Kogi and Kawakami,1997).
Workstation Design
Workstation design should respect and accommodate the differences in employees. It should
provide sufficient adjustability to accommodate the smallest and largest worker. There is a need
for a high degree of team-working and consequently adequate provision should be made for
formal and informal team spaces to allow staff to contribute to the development of teams
(Grandjean, 1987).
Vending Areas
Vending areas need to be close to the work-area with the provision of healthy meals, television
sets and discussion areas so that agents could break their concentration from the task at hand and
the monotony experienced. This encourages staff to take breaks and prevent a soiled workstation
(Croney, 1980).
Cleaning Services and Noise
The need for a clean environment is essential as agents are talking to customers the entire day.
Cleaning services should be made available to keep the environment clean. Plants should be
carefully placed at strategic locations that would serve as a décor and provide oxygen. Noise also
plays a role in the call centre. It should be at a manageable level where agents are able to
effectively communicate with the caller. A storage area should be created for the storage of
personal items. This would prevent the loss of personal belongings.
Position of the Monitor
The positioning of the monitor to the side of window light and/or in between overhead light
sources would reduce glare. The placement of desks directly underneath light sources should be
avoided. The screen or the operator should do not face an unshielded window. Removal or
reallocation of lighting sources such as one fluorescent from a bank of two can assist where
excess glare is noted. The lights and diffusers need to be clean regularly. Lights deteriorate with
age and accumulate dirt over their surface. Fluorescent light flicker indicates that either the tube
or the starter needs replacing. Contact with the facilities management office service desk to
arrange for replacement of fluorescent lights would be advisable. The aim is for even illumination
between adjacent areas. Extra task lighting can be added but should not have hard edges or
directly impinge on the computer user’s view or reflect onto the computer screens (MacLeod,
1995).
"Anti-glare" Screen Filters- Where all other efforts to correct lighting have not succeeded, use of
a screen filter may be necessary. A trial of the filter before purchase is recommended where
possible. Regular cleaning is also recommended. Adjustable brightness and contrast between the
background and the text is necessary. The screen needs to be free from reflections, screen flicker
and glare. The ability to rotate and tilt the screen is necessary. The screen needs to be at an
appropriate height above the work surface where the top line of text is just below eye level (15
degrees). No greater than six colours should be simultaneously displayed. The orientation of the
VDU will also influence posture, particularly the head and neck posture during the course of
viewing the monitor.
Noise
Excessive noise may increase staff stress and fatigue. General noise may be reduced by floor
carpeting and by locating office areas away from sources of external noise. The recommended
decibel range for office work is 55 to 65 decibels (dBA).
Hard surfaces such as glass walls or white boards would act to increase the reflection of noise.
Telephone or other conversations can be distracting in open plan offices. Sound absorbing
barriers may be considered if such noise is a problem. Some office groups follow their own "low
noise rules". Some office machines have high noise levels. Supervisors should ensure that noisy
machinery such as photocopiers are located away from the workstation (Pulat and Alexander,
1991).
Adequate personal space and storage for staff needs to be considered to prevent fatigue due to
constrained postures or movements. Correct placement of furniture in a work area ensures that
staff is not tempted to twist or reach with items over 4 kilograms. It is preferable to place a
secondary work space outside the maximum reach area so that staff are required to stand and
move around to reach items that should not be lifted whilst sitting. Standing and moving to a
position within easy reach of an object is preferable to over-stretching when reaching for objects
located beyond maximum reach. Appropriate height and sufficient shelving can also reduce the
need to bend or reach excessively to gather or store items. Poor spinal postures should be avoided
when reaching sideways and leaning down to the mobile drawer unit. The storage of heavy items
example water bottles, reams of paper on shelves should be around waist level. The storage of
items on the floor should be avoided as this could lead to lower back problems (Pulat and
Alexander, 1991).
Early Intervention
One of the main aims of designing effective, safe work systems and processes is to avoid the
development of musculoskeletal injuries or discomfort associated with work. Should discomfort
arise, early intervention to address health, safety or comfort concerns in the office environment is
vital to ensuring the best chance at resolution and can only be achieved through effective
communication between all stakeholders (Grandjean, 1987).
Staff Induction and Training
Computer users should be trained to adjust equipment and furniture appropriately and learn
appropriate keying/data entry techniques if this is the main requirement of their role.
Customer relation skills training such as “handling difficult people” should also be considered for
those staff in high demand phone and face to face roles to assist in the reduction of physical and
psychological tension often associated with these interactions (Ramdass, 2007).
Job Design
Supervisors also have responsibility for the design of the work in the positions under their control
to match human capacities.
Attention needs to be given to the following factors in designing safe work;
• Involve the workforce when designing jobs
• Rotation between a variety of tasks involving different muscles and joints
• Utilise user friendly software programs
• Plan staffing needs to cover foreseeable extremes of work pressure
• Appropriate allocation of work during leave periods. Expectation to accommodate
workers’ reduced capacity following extended leave or injury
• Consider rotation of tasks between employees
• Equipment provision and maintenance
Supervisors also need to ensure equipment requiring forceful use is maintained and replaced as
necessary, example hole punch, guillotine and chairs. Some office equipment such as hole
punches may require a drop of oil or lubricant occasionally. Blades may need sharpening and
chairs may also need regassing.
Employee Responsibilities
Employees should report symptoms of discomfort early to their supervisors.
When symptoms or concerns are identified the agent should contact their supervisor and if
necessary complete an Occupational Illness or Incident Report Form which would be reviewed
and investigated by the Risk Management Office. Late intervention can increase the risk of
developing chronic musculoskeletal conditions. Chronic conditions may lead to a person being
unable to maintain their employment despite subsequent changes to the tasks. Prompt action is
required to control any risks. This is necessary to prevent further risk for the staff member or
other staff performing similar tasks.
LONG TERM IMPROVEMENTS
The provision of better work surfaces with rounded front edges can cause mechanical stress
concentrations on the tendons of the forearms if workers rest their arms on them.
The possibility of adjustable work surfaces should be investigated to reduce stress on the tendons
of the forearms. In future facilities, it may be cost effective to buy a percentage of adjustable
work surfaces to adapt to anthropometric extremes. This would become more cost effective if the
company moves to more multiple shifts sharing the same stations.
Provide a small number of standing work stations than can be used during relaxation of muscles.
These standing stations could be placed along a side wall, and as long as the workers can
maintain their identity by logging on to one of these stations, they could be used for up to 20
minutes at a time on a voluntary basis for workers that tire from continuous sitting.
Provide monitor stands - Although the monitor heights in the current workstations appear
adequate, as workers are trained to better adjust their chair to their work-surface height to
promote the best body postures for keyboard work and writing, the need for adjustment of
monitor height would increase. These devices would be required by most by the taller workers.
These devices would also help if multiple shifts would be using the same workstation. However,
the nature of the work performed should be taken into account as one does not want to raise all of
the monitors if it would force people to look up and down more often.
CONCLUSION
Issues of workplace health and wellness are an ongoing priority for the Call Centre, which is the
commercial hub of an organisation. It is a joint organisation founded on strong membership from
the main workplace parties –business and labour. It is believed that approaches which promote
workplace health and wellness are in the best interests of both employers and workers – a clear
‘win-win’ strategy. In particular, in a period of anticipated growing skill shortages, those
employers who pay attention to workplace health issues would have a competitive advantage over
others in recruiting and retaining workers with much-needed skills.
Beginning with an ergonomics makeover, a good place to start is with the employees themselves.
Employee involvement in decision making around the wellness programmes occurs mainly
through survey mechanisms and feedback meeting with managers. Building relationships through
a team approach with a focus on the overall mission and vision of the organisation provides a
strategic starting point. Staff may complain about stuffy areas, ventilation, cramped workplace,
headaches, backaches, too much/little light, or uncomfortable temperatures. But what they really
need is the chance to concentrate, a degree of privacy, easy access to job tools without standing
up or reaching, the ability to adjust the workplace to their satisfaction, training and break rooms
to reduce monotony. Absenteeism and the reasons thereof could be a key area to address.
The changing of direct lighting into indirect lighting could reduce glaze, replacing painted walls,
with colourful fabric that absorbs sound, adding trees and plants would improve the ambience and
air quality (Ramdass, 2007).
Good ergonomics means more than putting in some new equipment. It needs to be an ongoing
programme that includes management leadership and training. The barrier to this achievement is
the attitude and cultural diversity among agents. Teambuilding, communication and a
participative management style has the potential to motivate the workforce to new levels of
productivity.
