generally speaking, four days off a month belongs to the hotel/catering industry, so it is calculated according to the algorithm in the hotel/catering industry. These four days are paid holidays, and seven days off, of which four days off are counted as paid holidays, and the other three days are personal holidays. The salary algorithm is salary = monthly salary/days of the month * (attendance days+four days off a month). Then there will be a problem here, that is, you have asked for three days' personal leave, and these three days' personal leave will not affect your 4-day Tian Yue holiday, which means that your 4-day monthly holiday will be less.
