Hi Buddy,
An employee can en-cash his/her Outstanding Earned Leave (EL) at the time of resignation or termination, But Factories act specify that an employee cannot accumulate more than 30 days of EL.
However if company policy allows an employee to accumulate more than what said in act than you may be eligible for en-cashing the outstanding leave in your account at the time of leaving the company.
With Regards
