A medical resident worked 207 hours of overtime in a month. His case highlights Japan’s continuing problem with karoshi - death by overwork.
I suspect they do get vacations but I suspect it can be quite stressful particularly for some people that don’t manage stress well.
Not that they get to choose, with entire quarters blocked off and never 14-day cushy vacations.
You think I got to choose? Mostly was ok we are not quite so busy and I going to take some days off. Typically your trying to work around all the employee days off. Ultimately the buck stops at you when you’re in that position.
