You can try to fight for it, but it doesn't mean much. Your final contribution may exceed your final personal income. 1. It is illegal to set a three-month probation period for a one-year contract. The labor inspection department estimates that it is too much trouble to persuade you to get a basic salary. Referring to Article 19 of the Labor Contract Law, if the term of the labor contract is more than three months but less than one year, the probation period shall not exceed one month; If the term of the labor contract is more than one year but less than three years, the probation period shall not exceed two months; The probation period of a labor contract with a fixed term of more than three years or without a fixed term shall not exceed six months. 2. The labor remuneration during the labor period shall be owned by the laborer, and it is illegal to agree not to pay the class fee and performance during the contract period. Class fee is labor income, and performance belongs to bonus. To calculate the composition of wages, of course, there must be records. No record, no evidence, no evidence. It is also a loophole in the contract.
