I only signed a labor contract with Dalian International Cooperation Co., Ltd., because I have not been arranged for an internship on the ship for a long time, I can cancel the contract and get my certificate back.
Hello. The "Labor Contract Law" clearly stipulates that the employer shall not detain the employee's ID card and other documents under any excuse. It is illegal for your company to detain your certificate and refuse to return it. You can go to your district (4 districts in the city) or the municipal labor inspection brigade to complain, and the result will be handled within 15 days.
With regard to liquidated damages, the Labor Contract Law stipulates the circumstances in which liquidated damages need to be paid. If the employer provides professional training and the service period is agreed, then you need to pay a certain penalty. According to your account, you only signed the labor contract and didn't stipulate the service period (see if your labor contract stipulates the service period), so you don't need to pay any liquidated damages. I hope I can help you ~
