in case of resignation during the epidemic period, the employer shall issue corresponding evidence. If an employee resigns during the epidemic period, the employing unit shall provide the employee with evidence of dissolution or termination of the labor contract, and go through the formalities of transferring the relationship between files and social insurance for the employee within 15 days. When handing over the work, the employing unit must also settle the labor remuneration with the employee in accordance with the labor contract and pay the remaining wages to the employee in one lump sum. You can apply for arbitration to protect your rights and ask to continue to perform the contract. Because of the new situation, the arbitration and the court will support you to withdraw your resignation. Because after your resignation, the company only talked about the interview, and did not give you a written notice of termination of the contract, and even failed to transfer insurance to you. Because you know that you are still working in the company after April 22, both parties have cancelled the original resignation application by their own actions, so you need to keep it. In theory, the company can't dismiss employees without reason during the epidemic. Even if the employees who are isolated for treatment due to the epidemic have expired, the term of the contract should be automatically extended after the treatment. The enterprise shall pay the living expenses according to the regulations of the local government for the employees who have not formally joined the work in the unit.

: If the unit dismisses the workers because they are isolated, it is illegal to terminate the labor relationship, because the reason why the workers can't go to work normally is caused by force majeure. There are two options to defend the rights when being dismissed: you can file a labor arbitration and demand the restoration of labor relations; Require the unit to pay double economic compensation.

Legal basis: Labor Contract Law of the People's Republic of China
