How do eight people in the hotel arrange two days' work and two days' rest?

Personnel Monday Tuesday Wednesday Thursday Friday Saturday Sunday

Supervisor 1 White rest, white rest, white rest

Supervisor 2 rest, rest, rest

1 Rest at night and rest at night.

2 nights off, white night off, white night off.

3 rest, white night rest, white night rest

4 White night rest, white night rest

Five nights off, white night off, white night off.

6 rest, white night rest, white night rest

This is 3 people in the day shift and 2 people in the night shift. The foreman works on the day shift and has a rest, and the employees have a rest twice. Other changes will be very difficult.
