Understanding Resignation Acceptance and Relieving Letters
Submitting a resignation is your right. There are chances that the company may or may not accept your resignation. They might have invested a significant sum of money in a particular employee. Hence, when the resignation is accepted, their investment could go in vain. So, there are instances where the company may not accept someone's resignation in such cases.
If there is no problem, then the company may issue an acceptance of your resignation. As mentioned above, you need not insist on the company giving you a letter as such.
At the time of physical exit from the company, you can insist that the company issue a relieving letter. This depends on your request in your resignation letter regarding when you desire to be relieved.
When someone wants to exit the company, it is always better that they serve a resignation to the organization and get relieved properly.
The relieving letter will help you submit to your next organization, ensuring that you are no longer in service with your previous organization.
Therefore, there is no hard and fast rule that these steps need to be followed in each company.
