How to deploy hotel staff in off-season and peak season?

Recently, the house is being renovated. At first, everyone was busy. On April 20th, 10 people ate, twice a day. 6 yuan/person/meal, total 120 yuan. On April 24th, six people had dinner, a total of 72 yuan. The master who finished on the 26th should be finished, leaving only four finishing workers. The funny thing is that these workers in the back are not as fierce as before. Through observation, it is found that these workers are afraid of finishing their work too early. It will take some time to start working, so these people will be slow in the future. In order to save the construction cost and complete the construction progress quickly. I decided to keep the best chef and raise the cost of meals to 10 yuan. But also in charge of wine-occasionally handing out cigarettes. The effect is just different! Both efficiency and quality have come up. Finally, I calculated that it was expected to be completed in 4 days, and the result was 2 days ahead of schedule. According to the labor cost of a worker 100 yuan. I saved 400 yuan, and the food cost increased by 4 yuan per person on the original basis, and at the same time increased by 32 yuan. The last money saved is 368 yuan! After talking so much nonsense, does the landlord understand? Deployment is not just a matter of words, but also needs to be able to calculate. So that your boss and employees will be happy!
