In terms of occupational health and safety, stress is the misfit between a worker's needs and capabilities, and what the workplace offers and demands. Another definition is "the reaction people have to excessive demands or pressures, arising when people try to cope with tasks, responsibilities or other types of pressure connected with their jobs, but find difficulty; strain or worry in doing so". (Health and Safety Executive, UK).
- One in four people took time off due to stress at work.
- The most stressful conditions at work reported were management issues including lack of communication and consultation; increased workload; organisational change and restructuring; and job insecurity.
- People reported a range of symptoms. More than 60 per cent reported headaches; continual tiredness; anger and sleeplessness.
- Over half the respondents nominated better management, including more communication and consultation, as the solution to stress at work. Other solutions included less workload; less performance monitoring; better work organisation; more training; job security and better career opportunities.
Despite this, and the fact that stress has been recognised as a major occupational hazard by unions and government OHS authorities world wide, many Australian employers do little about the issue. In fact, the view of one of the largest employer organisations, the Australian Chamber of Commerce and Industry (ACCI), is that there is that "...in spite of the substantial amount of work by academics and researchers over the last 20 years or so, we are no closer to providing proof of a linkage between so called workplace stress and disease" (ACCI Press Release, January, 2002: Stress as a Community and Workplace Issue)
What are the causes of stress?
A 'good job' usually involves a measure of positive stimuli, which encourages the worker to perform well and gain job satisfaction as a result - this is not stress. Many jobs involve negative factors that put unwanted pressure (stress) on the worker, leading to adverse consequences. Stress is not a disease or injury in itself, but can lead to mental and physical ill health, and can also be a factor in workplace accidents.
Many work factors can be identified as potential causes of stress, or stressors, and most can be divided into three areas:
- Working conditions
- Doing the job
- Work relationships
| Working conditions | Doing the job | Work relationships |
| Too hot or too cold | Excessive workload or long hours | Bullying or harassment |
| Too noisy | Boring or repetitive work | Discrimination |
| Poor equipment / work station | Deadline pressures | Client hostility |
| Inadequate security | Too little training or support | Conflict with supervisors/ managers |
| Poor lighting | Confusion over, or too much, responsibility for others | Poor relationships with colleagues |
| Overcrowding | Lack of control over work | Lack of communication or consultation between manager and employees |
| Inflexible work schedules or unpredictable hours | Organisational change/relocation | Negative culture based on blame for and denial of problems |
| Toxic fumes and chemicals | Unnecessary monitoring of employees | |
| Vibration | Job insecurity | |
| Poor childcare facilities | Inadequate pay and conditions | |
| Poor maintenance | Confusion over priorities, timeframes and standards | |
| Inadequate or unclear procedures: eg disciplinary, promotion, transfer, etc |
Workers attempt to cope with stress in a number of ways and with varying degrees of success. However, if the person is consistently exposed to stressful situations, adverse consequences will result. When the body is exposed to a stress, the level of hormones in the body increases to mobilise energy resources in preparation to 'fight or flee' the situation. This response may be appropriate in the case of a Stone Age person confronted by a wild beast, but should be out of place in today's work environment.
What are the health effects of exposure to stress?
The symptoms of stress can include indecision, anxiety, depression, altered appetite, changes in weight, headache, backache, skin rashes and difficulty sleeping. They may lead to heart disease, ulcers and other long term ill health.
Diseases of the blood circulation system:
- Hyertension
- Coronary heart disease
- Angina
- Heart attacks
Diseases of the digestive system:
- Ulcers
- Colitis (inflammation of the bowel)
Other problems include:
- Fatigue
- Headaches, backaches
- Anxiety
- Depression
- Hostility and aggression
- Psychosomatic complaints
- Neuroses
- Cancer (research has associated major life trauma with a number of cancers, and recently a South Australian court found that workplace stress contribute to a worker's fatal bowel cancer)
Just as the ways the body reacts to stress can be harmful if stress is prolonged, so too are some of the ways which people can use to try to cope with stress. As levels of stress increase, so too can the consumption of alcohol, cigarettes and prescription/ non-prescription drugs.
