The company has three working places, and only three people have to go to work every day. Everyone is at a point. How can we arrange the holiday for three people reasonably?

But working six days a week and working overtime for one day can solve it. That is, the total monthly salary includes overtime pay for four or five days. Overtime pay can be set to double pay.

As for the three people, if the holiday time is arranged, they can change shifts freely, and all shifts are equivalent to overtime. If the shift time is inconsistent, you can draw lots to decide. However, each person is required to work no more than 16 hours per day.
