I signed a contract with Shenzhen Youlian Shipyard. But when I went to see the subcontractor, the salary was not what I said at the beginning. Now I'm going to another one. also

That contract is a piece of paper. Can I handle it myself? Not even temporary workers or migrant workers, they have no rights at all. Their salary is not paid every month. It depends on whether the foreman can settle accounts and whether he is willing to pay after the completion. Generally, the shipyard will deduct the foreman's warranty money, so it will not be paid in full in the end, and there is no promised salary.
