If his opening balance of PL was 15, and he has not availed any PL during the January-May period, certainly, he should be paid 15 days' salary as leave encashment. In addition to this, he is also entitled to leave and encashment proportionately for the period January to May, subject to service conditions. Normally, if we apply the principles of the Factories Act, he would be eligible for leave for the current year if he has worked for 100 days in a five-month period, and his leave for the current period shall be based on his physical days present at the rate of one day for every 20 days.
