Dear Ritika ji,
In most of the MNCs, they provide contractual types of appointments. For example, in Turnkey projects, they offer these jobs to respective organizations, each having its own set of leave rules and procedures. In the case of contractual employment, employees may receive CL, EL, Paid Leave, etc., depending purely on the administrative procedures in place. Whether an employee is eligible or not will be determined by the rules established there.
If the contract of employment is governed by the Contract Labour (R&A) Act, it will not be.
Regards,
