Security guards work three shifts on the first day and work the night shift the next day, so I can work the night shift the next day? I think I work more.

Middle shift: 16.00-24.00

Night shift: Calculate from 24.00 to 8.00, then you will work the morning shift and night shift on the first day, then the morning shift and night shift on the second day, and then four shifts on the second day. But in theory, you can only work three shifts in two days. But did you two security guards have any other consultations? If there is no other negotiation, just look at the number of times you go to work these two days. You are working overtime.
