Dear Ritika,
Basically, ur information is short, whether ur unit is factory or establishment' if it is factory, employee is not entitled for earned leave as it will be worked out after completing 240 days of service,
if it is establishment under shops & comm.establishment act and governed by the state govt. then what provisions for leave in ur State be checked. but remember one thing what policy in respect of leave has been adopted by ur organization is important.There is no provision of casual leave in factory act as well shops & comm. establishment act. so, the leave may be treated as leave without pay.
regards,
KIRAN KALE
