El encashment in case if resignation

Hello sir,
I am working in Militry Engineering services under ministry of defence(central government employee)
as junior engineer since may 2013. I want to know whether i can avail el encashment in case of resignation or not?
As i asked in my office they told i cann't avail but i studied in internet that one can avail el encashment in case of resignation. Please clarify me with book reference or policy letter for central government employee.

Hi Anoop,
EL encashment is a benefit offered by the company. Better check your offer letter or the company's leave policy
