Being the boss might mean more money and challenging work but it can also cause damage to physical and mental well-being, according to a Canadian study.

For years studies have shown people in lower-status jobs generally have higher rates of heart disease and other illnesses and die earlier than those in higher-status positions while job authority has shown no relationship with workers’ health.

But University of Toronto researchers, using data from 1,800 US workers, found the health of people in higher positions is affected by work as they are more likely to report conflicts with co-workers and say work disturbs their home life.

However, the positive aspects of having a power position at work, such as higher status, more pay and greater independence, seemed to cancel out the negative aspects when it came to people’s physical and psychological health.

These latest findings, reported in the journal Social Science & Medicine, suggest that the advantages and disadvantages authority positions basically cancel each other out, giving the general impression that job authority has no health effects.

For the study, the researchers surveyed participants about various aspects of their work, life and well-being. Job authority was judged based on whether a person managed other employees and had power over hiring, firing and pay.

Physical health complaints included problems like headaches, body aches, heartburn and tiredness. Psychological complaints included sleep problems, difficulty concentrating and feelings of sadness, worry and anxiety.

“This isn’t to suggest that having authority is ‘bad’—in fact, we show it has benefits ... but it is important to identify the negative sides and deal with them.” researcher Scott Schieman said.  

Schieman said conflicts with co-workers or involvement of work into home life may destroy at physical and mental well-being by creating stress.

“These are key stressors that can tax individuals’ ability to function effectively,” Schieman said.
