Your query is incomplete. You have not mentioned how you have separated from your previous employer. Is it due to resignation, removal from service, termination, dismissal, voluntary retirement, or superannuation?
Superannuation and Leave Encashment
In the case of superannuation, the maximum limit/portion of earned leave allowed to be accumulated at any point in time is permitted to be encashed, subject to a maximum of 300 days. The Department of Public Enterprises (DPE) has issued specific guidelines on this issue. Companies may frame their own leave rules, keeping in view the broad parameters defined by the DPE.
Other Cases of Separation
However, in cases other than superannuation, employers do not provide the benefit of encashment of earned leave based on the simple principle that if you were in service, you would avail leave. Encashment can only be claimed if the requested leave has been denied in writing, and you have sufficient proof to support your claim.
If the amount is substantial and you have proof, you can seek legal recourse; otherwise, it is advisable to move on and redirect your energy and resources towards more productive activities.
