Classification of the causes of stress at work
Stress affects people at work in many ways and the causes of stress are diverse. These causes can be associated with elements of the physical; environment, such as open plan office layouts, the way the organization is managed, relationships within the organization and even inadequate work equipment. The causes can be classified as follows.
1 The physical environment
Poor working conditions associated with the following can be frequent sources of stress in the workplace:
● Insufficient space to operate comfortably, safely and in the most efficient manner;
● Lack of privacy which may be disconcerting for some people;
● Open plan office layouts, resulting in distractions, noise, constant interruptions and difficulty in concentrating on the task in hand;
● Inhuman workplace layouts requiring excessive bending, stretching and manualhandling of materials;
● Inadequate temperature and humidity control, creating excessive discomfort;
● Poor levels of illumination to the extent that tasks cannot be undertaken safely;
● Excessive noise levels, requiring the individual to raise his voice; and
● Inadequate ventilation, resulting in discomfort, particularly in summer months.
2 The organization
The organization, its policies and procedures, its culture and style of operation can be a cause of stress. Culture is defined as ‘a state or set of manners in a particular organization’. All organizations incorporate one or more cultures, which may be described as, for example, friendly, hostile, unrewarding or family-style. Stress can be associated with organizational culture and style due to, for instance:
● Insufficient staff for the size of the workload, resulting in excessive overtime working;
● Too many unfilled posts, with employees having to ‘double up’ at tasks for which they have not necessarily been trained or instructed;
● Poor co-ordination between departments;
● Insufficient training to do the job well, creating uncertainty and lack of confidence in undertaking tasks;
● Inadequate information to the extent that people ‘do not know where they stand’;
● No control over the workload, the extent of which may fluctuate on a day-to-day basis;
● Rigid working procedures with no flexibility in approach; and
● No time being given to adjust to change, one of the greatest causes of stress amongst employees.
3 The way the organization is managed
Management styles, philosophies, work systems, approaches and objectives can contribute to the individual stress on employees, as a result of:
● Inconsistency in style and approach by different managers;
● Emphasis on competitiveness, often at the expense of safe and healthy working procedures;
● Crisis management all the time, due to management’s inability, in many cases, to plan ahead and to manage sudden demands made by clients;
● Information being seen as power by some people, resulting in intentional withholding of key information which is relevant to tasks, procedures and systems;
● Procedures always being changed due, in many cases, to a failure by management to do the basic initial research into projects prior to commencement of same;
● Over-dependence on overtime working, on the presumption that employees are always amenable to the extra cash benefits to be derived from working overtime; and
● The need to operate shift work which can have a detrimental effect on the domestic lives of employees in some cases.
4 Role in the organization
Everyone has a role, function or purpose within the organization. Stress can be created through:
● Role ambiguity.
● Role conflict .
● Too little responsibility
● Lack of senior management support, particularly in the case of disciplinary matters dealt with by junior managers, such as supervisors, and
● Responsibility for people and things which some junior managers, in particular, may not have been adequately trained to deal with.
5 Relations within the organization
How people relate to each other within the organizational framework and structure can be a significant cause of stress, due to, perhaps:
● Poor relations with the boss which may arise through lack of understanding of each other’s role and responsibilities, attitudes held, and other human emotions, such as greed, envy and lack of respect.
● Poor relations with colleagues and subordinates created by a wide range of human emotions.
● Difficulties in delegating responsibility due, perhaps, to lack of management training, the need ‘to get the job done properly’, lack of confidence in subordinates and no clear dividing lines as to the individual functions of management and employees.
● Personality conflicts arising from, for example, differences in language, regional accent, race, sex, temperament, level of education and knowledge.
● No feedback from colleagues or management, creating a feeling of isolation and despair.
6 Career development
Stress is directly related to progression or otherwise in a career within the organization. It may be created by:
● Lack of job security due to continuing changes within the organization’s structure.
● Overpromotion due, perhaps, to incorrect selection or there being no one else available to fill the post effectively.
● Underpromotion, creating a feeling of ‘having been overlooked’.
● Thwarted ambition, where the employee’s personal ambitions do not necessarily tie up with management’s perception of his current and future abilities.
● The job has insufficient status.
● Not being paid as well as others who do similar jobs.
7 Personal and social relationships
The relationships which exist between people on a personal and social basis are frequently a cause of stress through, for instance:
● Insufficient opportunities for social contact while at work due to the unremitting nature of tasks;
● Sexism and sexual harassment;
● Racism and racial harassment;
● Conflicts with family demands; and
● Divided loyalties between one’s own needs and organizational demands.
.8 Equipment
Inadequate, out-of-date, unreliable work equipment is frequently associated with stressful conditions amongst workers. Such equipment may be:
● Not suitable for the job or environment;
● Old and/or in poor condition;
● Unreliable or not properly maintained on a regular basis, resulting in constant breakdowns and down time;
● Badly sited, resulting in excessive manual handling of components or the need to walk excessive distances between different parts of a processing operation;
● Of such a design and sited in such a way that it requires the individual to adopt fixed and uncomfortable posture when operating same (see Chapter 7); and
● Adds to noise and heat levels, increasing discomfort and reducing effective verbal communication between employees.
9 Individual concerns
All people are different in terms of attitudes, personality, motivation and in their ability to cope with stressors. People may experience a stress response due to:
● Difficulty in coping with change;
● Lack of confidence in dealing with interpersonal problems, such as those arising from aggression, bullying and harassment at work;
● Not being assertive enough, allowing other people to dominate in terms of deciding how to do the work;
● Not being good at managing time, frequently resulting in pressure from supervisors and other employees to ensure the task is completed satisfactorily and on time; and
● Lack of knowledge about managing stress.
