Section 80 of the Factories Act
Section 80 of the Factories Act reads as follows:
80. Wages during leave period.—(1) For the leave allowed to him under [section 78 or section 79, as the case may be,] a worker shall be entitled to wages at a rate equal to the daily average of his total full-time earnings for the days on which he actually worked during the month immediately preceding his leave, exclusive of any overtime and bonus but inclusive of dearness allowance.
In my opinion, when considering full-time earnings (Gross wages) for the period of leave availed by him/her, the same logic can be applied for leave encashment (Gross wages).
Limitations on Leave Carry Forward
Having said that, Section 79 limits the carry forward of unavailed leave to the succeeding year subject to a maximum of thirty days in the case of an adult. This means that any earned leave accumulated beyond thirty days will lapse.
In such a case, if you consider Gross wages for Leave Without Pay (LWP) computation, you can follow the same for leave encashment. However, if your LWP computation is on Basic + DA alone, then in my opinion, you can restrict leave encashment payment to Basic + DA.
