Leave pay calculation under the UAE employment contract

Dear Madam.

My JAFZA Employment Contract is an unlimited free zone contract.

My services have been arbitrarily terminated on 09 Dec. 2018, and after having served the 90 days paid notice period, my tenure ended on 08 March 2019.

I am now in the process of finalizing my end of service benefits, and there is a clarification required in regards to the basis of computation of the benefits. Queries are as under.

Leave pay due to termination:

I have 25 days unutilized leave which I intend to encash. What is the basis of computing the value of this leave pay?

Would it be on the basis of:

a.) gross monthly salary (which includes the latest basic salary + housing allowance + transport allowances)

b.) or on the basis of latest basic salary + housing allowance

c.) or on the basis of just the latest basic salary?

Could you please clarify and provide me with the correct latest updated UAE Labor Law article ref. # 79 for the correct interpretation of the basis of calculation for the above leave pay.
