How to calculate the salary and overtime pay of Dezhou Lehua Ceramic Sanitary Ware?

Just opposite Shuanghui Food Factory in Dezhou Development Zone, on Jinghua Road. But I advise you not to go to this company. It's not good. First of all, the system inside is inhuman, the working hours are too long, and there is no overtime. The assigned work must be completed, and overtime will be considered at 12 pm. In addition, the small leaders inside are particularly greedy. New employees should be treated when they go, and so should old employees. When they get paid, they must feed the dog. Working hours often reach 12 hours, so the salary is actually not high, and there are many problems in breaking the company, and one day off a month. There are so many systems that there is not even a carport for employees. When it rains, the cars are soaked, and people who work at noon have little time to eat.
