Vacations and holidays were legally mandated in China. Yet, at Chinese hospitals, vacations were nothing more than a myth to the resident doctors and rotation doctors who were like dogs. The hospitals technically wouldn't force the lower-ranking doctors to work overtime on vacation and holiday days, but the higher-ranking doctors, department directors, and hospital administration director would all be watching the lower-ranking doctors' work attitude. The lower-ranking doctors would all "voluntarily" choose to work overtime then! It was by their own choice, as nobody would force them. Of course, they could choose to not work overtime, but it was likely that they would then lose their job or be left out of promotion opportunities.
