The following article on stress on the job is reprinted from the Canadian Centre For Occupational Health and Safety, August publication. Stress and fatigue are killers at work. The more we know, the better able we are to attack the problem and save lives. By Ron Labonte he relationship be- tween stress and health is almost as complex a Gorgon’s Knot as that be- tween stress and working conditions. The American Academy of Science several years ago identified stress as a factor in 90 per cent of illness. A growing body of evidence supports the new science of “psychoneuro- immunology,” which holds that psy- chological states (happiness, con- nectedness with others, absence of anxiety) exert a potent influence on our immune system and, hence, our ability to cope with disease states ranging from cancer and heart dis- ease to the common cold. Stress and cardiovascular disease (Canada’s no. 1 cause of death and disability) show strong scientific ties. Numerous studies have found that persons with high stress scores are more likely to have high blood and serum cholesterol, and a higher prevalence of angina, myocardial » v ACD AX dollars, jobs and headaches. In a province such as B.C. where 25 per- cent of the workforce is dependent on the forest sector in one way or another fires can mean economic ruin. Fires hurt more than just the economy though. They threaten wildlife, water supplies and can have a negative long-term effect on the infarction (heart at- tack) and coronary heart and artery dis- ease. Most of these stud- ies have been “cross-sec- tional”, a slice-in-time that makes establishing cause and effect diffi- cult. (Did the stress cause the heart disease or vice versa?) But because several have been “prospective”, going forward in time and compar- ing disease prevalence among per- sons with and without high stress scores, there is general agreement that stress, for all its definitional problems, should be considered an important risk factor in heart dis- ease. That the stress response syn- drome loads the circulatory system with gooey cholesterols and con- stricts the circulatory system into high blood pressure makes the con- nection biologically | common- sensical. It’s difficult to quantify the heart disease risk of certain stress condi- tions because of the vast number of tourist industry. A charred forest does not make a pretty sight. We in Canada have an impressive track record when it comes to fight- ing fires. Over 80 percent of all fires are brought under control within 24 hours of detection. But, it is expen- sive. In B.C. for instance, fire- fighting costs an average of 37 mil- lion annually. Each year we lose over 100,000 hectares and consume 4.65 million cubic metres of timber. That represents a lot of jobs. Education is helping to cut down on the number of fires but, where there are forests there will always be fires. Lightning is still decimating more acres than are people and there is little that can be done about that. But as we refine our firefighting methods and detection the damage can at least be controlled. other “co-factors” — smok- ing behaviour, eating and exercise habits, degree of social support, extent of stress- coping practices, etc. In general, though, cardiovascular disease rates are two to four times higher among lower-income, occupational and edu- cational groups, those persons most likely to encounter the powerless- ness, isolation and suppressed or inner-directed anger that have be- come the toxic hallmarks of “stress”. Finally, a word on “eustress” or “good stress”: Accordingly to many stress researchers, casting the con- cept in bipolar terms (certain types of amounts of stress are good, others are bad) only makes muddier the already murky waters.

Union members comprised 36.6 per cent of Canada’s non-agricultural paid workers, a decline from the level of 37.6 per cent in 1987. The Canadian Labour Congress remains the largest central labour organization, with an affiliated mem- bership of 2.2 million, or 58.1 per tween good and bad stress, and the Canadian Institute of Stress continues to define it in value-neutral terms as “purely and simply, a very powerful fuel”. There is, however, no empirical evidence to support a bipolar theory. Stimulation, challenge, variety and control may be the bones and muscle of a good job, but they are not examples of “good stress”. Stress, in common usage and scien- tific inquiry, is the pathological tax- ing of humans beyond their physical and psychological capacity. As with any occupational hazard, the first choice in control should be elimina- tion of workplace stressors, the sec- ond “control along the path” (in- creased worker participation and social support), and the third “con- trol at the worker” (personal stress- coping and relaxation techniques. cent of unionized workers. The ten largest unions in Canada maintained their ranking from a year earlier. Those recording an increase in membership were: the Canadian Union of Public Employees (CUPE), the National Union of Provincial Government Employees (NUPGE), the United Food and Commercial Workers (UFCW) and the Social Affairs FederationInc. (SAF). Mem- bership declined in the Public Ser- vice Alliance of Canada between 1987 and 1988 and was unchanged in the other five largest unions. These and other statistics, to- gether with information on interna- tional and national unions, indepen- dent local organizations, central lab- our congresses and world labour organizations are included in the Directory of Labour Organizations.
