The usual assumption is that bosses demand it. YouGov's data says otherwise. Asked how often they check work email on holiday, British workers who use email for work split 40% never, 16% rarely, 19% sometimes, 15% often and 10% very often. Asked what they would prefer if the choice were theirs, 80% said they would rather switch off completely and only 17% would rather stay on top of things. But asked whether their manager would expect them to check in, just 5% said definitely and 10% probably, against more than four in five who said their manager probably or definitely would not. YouGov's own write-up concludes the pressure 'could be self-inflicted'. One group breaks the pattern: among those who check very often, 47% actually prefer staying informed, close to the 50% who would rather disconnect. So a single behaviour contains two different populations: a minority who want the information, and a much larger group doing something they say they do not want to do.
