More than a year since millions of Canadians logged into a work-from-home routine, many are still struggling to log out. These days, there is a “sense of obligation” to stay connected, but workers need the right to disconnect, said Hassan Yussuff, the president of the Canadian Labour Congress. “We have to find a way to change that attitude,” he said. “Equally, we have to provide legal protection for people so they don’t have that sense of guilt if they didn’t respond to an email, or didn’t get on their computer, or didn’t answer their phone.” Now, with a new study suggesting that constant connection is more dangerous than you think, experts say even more attention is needed. Long work hours are killing hundreds of thousands of people a year, according to the World Health Organization. The first-of-its-kind global study found 745,000 people died from stroke and heart disease associated with long working hours in 2016 — an increase of nearly 30 per cent from 2000.
