Hi, the Factories Act states that during the initial year of service, no leave is allowed under the Factories Act. In the subsequent year, an employee will get leave at the rate of one day per 20 days worked in the previous year, but only if they actually worked for 240 days in that previous year. It is not about earning one day after every 20 days of work and carrying it forward or availing it after every 20 days. The calculation is done after the closure of a calendar year, and only those who have actually worked for 240 days (days of holidays, weekly off, leave due to employment injury, lay off, maternity leave days in the case of women, etc., are taken as days worked for this purpose) are eligible for such leave. This is referred to as annual leave with wages/earned leave.
Therefore, someone who works for 230 days in the year 2007, was laid off for 6 days, and was on leave for temporary employment injury for 4 days, will be eligible for leave in 2008. However, they will only earn leave for the 230 days they had worked.
