Hi Priyanka,
Anyways, an employee who has absconded will not be putting in his 100% effort even if you find him and file a suit against him to ask him to work. So, it's better to leave him as he wishes. Let's come to the point.
For retention, HR can include some special clauses in the appointment letter itself when appointing an employee. For example:
"You are liable to inform HR or your reporting authority properly when deciding to resign and quit the services. Uninformed absence from work will be considered as abscondism. Therefore, no relieving letter will be issued if you fail to resign properly and serve the notice period."
"The company is liable to pay 9000 Indian Rupees on completion of every six months of your tenure. If you happen to get relieved within the duration of six months, the company shall not be liable to pay Rs 9000."
The first clause aims to make the employee serve the notice period and get relieved, while the second option is to encourage the employee to stay with the company by offering a retention bonus based on their cadre and designation. It is implied that Rs. 1500 will be retained as the retention bonus every month, and at the end of every six months, it will be given as a total sum of Rs. 9000.
You can also find a way similar to this, get it approved by your boss, and implement the same.
Thanks and Regards,
