A plant/factory should be registered under the Factory Act without saying, and the leave will be regulated in accordance with the Factory Act. In the Factory Act, it clearly stipulates that if a worker works for 20 days, 1 day of leave is earned by him. It means that if a worker has worked 240 days or more in a calendar year, he shall be allowed 1 day of EL/PL for every 20 days worked. So, his earned leave will be calculated accordingly.
If an office/establishment is registered under the local Shop & Establishment Act, the leave will be permissible as per such Act.
If there is any agreement between the management and the union pertaining to wage settlement, including leave and other matters, then it will be regulated in accordance with the terms of settlement. But under no circumstances will leave be less than the statutory provision of the aforesaid Act. If both parties have agreed and signed a settlement, allowing SL and CL apart from EL, then they are bound to follow the same as per the terms of the agreement.
