Of course it's illegal. Working and getting paid is a basic human right. In addition (1) depends on time. Article 41 of the Labor Contract Law of People's Republic of China (PRC) * * * Due to the needs of production and operation, the employer may extend the working hours after consultation with the trade union and the laborer, and generally the daily working hours shall not exceed one hour; If it is necessary to extend the working hours for special reasons, the extended working hours shall not exceed three hours a day and thirty-six hours a month under the condition of ensuring the health of the workers. -Does the company work too much beyond normal working hours? (2) Look at the salary. Article 50 Wages shall be paid to labourers themselves on a monthly basis in the form of currency. The wages of workers shall not be deducted or delayed without reason. As for the standard of overtime pay, the law also clearly stipulates that overtime work will definitely not be done in vain. (3) Of course, you should also look at the labor contract you signed with the company. If you have agreed to these contents before (for example, you must meet certain standards-your overtime return visit is only because you can't finish it within the specified time, so you have to finish it another time), it will be more troublesome. You should start with the labor contract and see whether the content of such contract is reasonable from the source (contract). (4) The company may have a certain reward and punishment system, but it must be protected by law, otherwise it will be invalid. You can communicate with the company (trade union or relevant departments), and if you can't solve it, you can go to court again ~
