Regarding the deduction of social security for the year-end bonus, can medical insurance sue?

1. It is illegal for the company not to buy social security for its employees, so it is not necessary to obtain the consent of the employees.

2. There is no legal provision on how much year-end bonus the company issues, so the company deducted you 1.200 yuan. You should have proof.

According to the labor contract law, the company must sign a labor contract with its employees within one month. If the company doesn't sign a labor contract, you can complain to the local labor bureau and demand to pay double the salary for the working hours (minus one month) during the unsigned labor period, terminate the labor contract and leave with pay, as long as you have evidence to prove that you have worked there for 2 years.
