The Canadian Province of Quebec studied the major occupational groups at risk for mental health problems. And not surprisingly, occupations with the lowest levels of decision-making freedom on the job had the highest elements of risk.
The highest-risk jobs were in road transportation. That is, taxi drivers and bus drivers. But NOT truck drivers.
Following them are jobs in textile, leather and fur manufacturing and repairing. Then comes housekeeping and maintenance workers, followed by painters, followed by insulation and waterproofing workers.
At lowest risk, ahem, are data processors, editors, and university professors.
