Leave and confirmation are not related. In a factory kind of organisation, an employee becomes eligible to leave only when he works for 240 days in the preceding year of 12 months or in respect of those who joined during the year, a minimum 20 days in a month. The leave entitlement has nothing to do with probation and confirmation. That means, even if he is not confirmed, he should get leave with pay if he has had the minimum service in the year.
In a shop or commercial establishment the leaves are regulated by the state Acts governing shops and commercial establishments. Under the various state Acts, a new joinee as a probationer is entitled to 12 days each of casual and sick leaves for 12 months. Similarly, after 12 months service, he shall get 12 days earned leave. This can also be like one day for every 20 days worked in the preceding year. Anyway, it has no reference to the status of employees. Accordingly, for EL/ PL the only qualifying condition is that the employee should have 12 months service.
