Send resignation letters, envelopes and stamps to the company? I want to send my resignation letter to the company on the first day after the Spring Festival. I don't know how to send it. Should I use envelopes and stamps? Yes If you want to resign, you only need to submit your resignation letter to the labor and personnel department of the employer by registered mail 30 days in advance (remember: keep the registered receipt as evidence), without the consent of the employer. If you continue to work for 30 days, you can stop working on the 3rd1day. You have the right to ask the employer to handle the resignation procedures, which should be handled by the employer (Article 3 1 of the Labor Law and Article 37 of the Labor Contract Law). At the same time, pay off your salary in one lump sum (Article 9 of the Interim Provisions on Wage Payment) and issue you a certificate of dissolution of the labor contract (Labor Contract Law).
