Immediate Employer :

“Immediate Employer” means a person, in relation to employees employed by or through him, who has undertaken the execution on the premises of a factory or an establishment to which this Act applies or under the supervision of principal employer or his agent, of the whole or any part of any work which is ordinarily part of the work of the factory or establishment of the principal employer or is preliminary to the work carried on, in or incidental to the purpose of any such factory or establishment, and includes a person by whom the services of an employee who has entered into a contract of service with him are temporarily lent or let on hire to the principal employer and includes a contractor. [Section 2(13A)] It would not be necessary that the work undertaken by immediate employer should be in the premises where the factory of principal employer is situated (1997-II LLJ 31 Pat.).
