Annual Leave Provision in the Factories Act 1948
There is some confusion regarding the Annual Leave ("Earned Leave or Privilege Leave") provision in the Factories Act 1948. It is clarified that it is not necessary to work for 240 days in a calendar year before starting to earn Annual Leave. The Act provides that a worker whose service commences other than on the first day of January is entitled to leave with wages at the rate of one day for every twenty days worked if they have worked for two-thirds of the total number of days in the remainder of the calendar year.
In subsequent years of service, since the employee is in service on 1st January, the completion of 240 days of actual working is necessary to earn leave at a rate of 1:20. So, regarding your question, presuming you are a factory as per the Factories Act 1948, you need to verify whether the employee has actually worked for two-thirds of the total number of days in the remainder of the calendar year (from June to December 2020), and that number of leaves could be credited to the employee's leave account at the start of the year 2021.
In January 2022, the employee would get credited leave quantum based on 1:20 for the number of days worked, provided the days of actual working are 240 or more in the calendar year 2021. For the purpose of computing 240 days, any days of layoff, by agreement or contract, or as permissible under the standing orders; in the case of a female worker, maternity leave for any number of days not exceeding twelve weeks; and the leave earned in the year prior to that in which the leave is enjoyed, shall be deemed to be days on which the worker has worked in a factory, but they shall not earn leave for these days.
