Dear
In that case we are to go through section 79 Explanation 2(2) which runs as under:
A worker whose service commences otherwise than on the first day of January shall be entitled to leave with wages at the rate laid down in clause (i) or, as the case may be, clause (ii) of sub-section (1) if he has worked for two- thirds of the total number of days in the remainder of the calendar year.
Thus if the employee fulfills this condition then he will be entitled to EL @ one for every twenty days. For more details you may also go through section 79 of the Factories Act, 1948.
