For the first time, two people go to work. After eight hours, the second person gets off work, the third person goes to work, and after eight hours, the first person gets off work and the second person goes to work.

That is to say, everyone goes to work 16 hours and takes 8 hours off. Or go to work for 8 hours and rest for 4 hours. Or 1 and 2 go to work, 1No. 12 hours later, go to work on the 3rd, 12 hours later 1 No.2. That is to say, last 24 days 12.

Suppose three people, A, B and C, work together for 8 hours, then work in BC for 8 hours, and finally work in AC for 8 hours, so that all three people work for 16 hours and have a rest for 8 hours, or only one of the three people is allowed to work for more than 16 hours.

Daily scheduling skills

Take pharmacies and supermarkets as examples. The business hours of these places are generally from 8: 00 am to 2 1 pm. If a person finishes it, he needs to work 13 hours, which is seriously beyond the working hours stipulated by law, which is a severe test for the physical strength and energy of the workers, and it is illegal for the operators.

In order to avoid illegal activities, these places generally adopt a two-shift work system. The first shift starts at 8: 00 a.m. and ends at 4: 30 p.m. 14: The second shift starts at 4: 30 pm1and ends at 2: 00 pm. There will be a difference in time.

Through the implementation of the two-shift system, the workload of workers is reduced, the working hours of workers are reduced, and the illegal behavior of operators is avoided. Although the wages of workers will be relatively lower, the work will be relatively easy.
