In life, there is such a situation when, having decided to quit, you wrote a statement of your own free will, and you suddenly had objective reasons not to leave your job, or you simply changed your mind. To stop the process of your dismissal, do the following.
Inform the administration in writing of your decision not to quit. To do this, write a statement addressed to the director of the company. This must be done before the expiration of the two-week notice period of voluntary dismissal. The content of the statement will be as follows: "I ask you to withdraw the statement of my dismissal of my own free will from such and such a date." Put a number, a signature. Make a copy of your application for withdrawal, or write in duplicate. Ask your secretary or HR officer to date and sign your copy of the statement.
Submit your application to management. Now you cannot be fired, even if the manager did not sign your revocation letter. Otherwise, go to court within a month from the date of dismissal with a statement of claim for violation of labor laws. By a court decision, you will be reinstated in your job and paid for earnings not received as a result of illegal dismissal.
Check with the HR department to see if another employee has been invited to your place in writing by way of transfer. Keep in mind that if this employee has already quit his previous job, the application for revocation will not be signed to you, you will be fired at the appointed time and you will not be able to do anything about it, since according to labor law, the administration has no right to refuse another employee invited in writing in order of transfer to your place.
