Dissolution of the labor contract is the right granted to workers by Articles 37 and 38 of the Labor Contract Law. If you want to terminate the labor contract, you don't need to apply to the employer and get the approval of the employer. It is your decision to terminate the labor contract. You only need to notify the employer according to law to prove that your written notice has arrived. Then your procedure for dissolving the labor contract conforms to the provisions of the Labor Contract Law, and you are not liable for compensation as stipulated in Article 90 of the Labor Contract Law. If the employer has one of the situations mentioned in Article 38 of the Labor Contract Law, you not only need not advance 30 days, but also can request economic compensation according to Article 46 of the Labor Contract Law. If the employer does not infringe upon your legitimate rights and interests, there is no economic compensation for you to propose to terminate the labor contract. As long as there is no Article 25 of the Labor Contract Law, it is illegal to stipulate that the liquidated damages shall be borne by the workers.
After the decision (or notice) to terminate the labor contract is submitted, whether it is approved or not is not important. The key is for someone to sign for it as proof of dissolving the labor contract according to law, otherwise the bad company will say that you left your job voluntarily and didn't hand in your resignation report, so it's hard for you to make a statement. You submit the decision or notice to terminate the labor contract 30 days in advance (3 days in advance of the probation period, the same below). If no one signs for it, you can send it to the post office by courier, fill in the "Decision Letter (or Notice) of Dissolving the Labor Contract" in the "Name of Internal Parts" column, and keep the receipt as evidence, plus the labor contract is enough. If the employer pays your salary on the last day of work, you can apply to the local labor dispute arbitration committee for arbitration.
