Second study finds COVID-19 protection at work is linked with workers' mental health

Levels of anxiety and depression are higher when workers feel they lack COVID-19 protection on the job. That's according to a study of Canadian workers not in health-care, a second in a pair of studies conducted by the Institute for Work & Health (IWH) and Occupational Health Clinics for Ontario Workers (OHCOW) in the early months of the pandemic. Mental health was even poorer among essential workers who said they had no protection at work than among those who had lost their jobs since the start of the pandemic, according to this second study.

Inequalities growing in Canada in rates of early death

Although early death rates have fallen for nearly all socioeconomic groups in Canada, they're falling faster for some more than others. A new study by Dr. Faraz Vahid Shahidi, IWH Mustard post-doctoral fellow, finds inequalities in premature mortality have widened over 25 years between people with the highest and lowest income and education levels.
