Class four is to divide employees into four classes, two shifts every four days. One day shift and one night shift, (65438+ 02 hours per shift) plus 2 days off, and 4 days is a cycle.

The first day: class one goes to work from eight to twenty, and class two goes to work from twenty to eight.

The next day: Class 3 goes to work from 8: 00 to 20: 00, and Class 4 goes to work from 20: 00 to 8: 00.

Day 3: Class 2 goes to work from 8: 00 to 20: 00, 1 Class 20: 00 to 8: 00.

Day 4: Class 4 goes to work from 8 to 20, and Class 3 goes to work from 20 to 8.

Day 5: 1 Class 8:00-20:00, Class 2: 20-8: 00.
