Dear Sakshi,
If the employee has not properly handed over the charge of his duties, the process of separation would be incomplete. Without completing this process, how can he be issued a relieving letter?
If the employee joined in April 2020, there was sufficient time to have him sign the Appointment Letter. Why was this opportunity missed from December 2020 to March 2021? This oversight is on the part of the company.
While separating from the company, the employee is expected to return any company property in his or her possession. You may create a list of items the employee needs to hand over. Send the hard copy of this letter to his hometown address by Speed Post. After sending, scan the office copy of the letter along with the Speed Post receipt and send it by email. Clearly inform the employee that unless he completes his discharge process, no relieving letter will be issued.
If he fails to join his new company on 24th May 2021, it will be due to his recklessness. Your company is not responsible for that.
Policy on Handing/Taking Over
Lastly, it appears that your company does not have a proper "Policy on Handing/Taking Over." You may frame this policy and circulate it to all employees. Secondly, as soon as the employee submits a resignation, start acknowledging the letter. In the acknowledgment letter, outline the procedure for discharge. Clearly state to whom he will hand over the charge, when and how he will do it, and what company property is outstanding against him.
Take this incident as a learning opportunity to prevent similar situations in the future.
Thanks,
Dinesh Divekar
