Laws Of Third Party For Their Employees.

Hi,
One of my friend is on third party payroll & his site location is not mention in his offer letter.
His third party company mentioned their company name only in the offer letter & deputed him in the other site (third party site).
Please tell so we have a rights to ask them to mentioned the third party name in the offer letter or is there any law which shows that employer should mentioned the third party company name in the offer letter of the employee. Because the HR is declined to mentioned the Third party company name in the offer letter & harass my friend by saying they will fired him from his designation.
Please Help.

Hello...
In my opinion, it is not mandatory to mention the third party location in the offer letter. The third party location may keep changing during his tenure of working. This issue should not be of any concern since he has the offer letter of the company on whose payroll he is working and all the statutory obligations are met by them.
However, at the time of separation he can request his employer to mention the the clients name in the service certificate.
Hope your query is answered.

Even I'm of the same opinion, it need not be mentioned in the offer letter.
Any how his hiring and firing should be guided as per his appointment letter.

Sherry
