EPF & MP Act, 1952 covers whole of India except J&K state.
In PF Act, explanation of an employee is detailed below:-
"Contract labour is included but casual labour is excluded for counting the strength of employees. An apprentice is only a learner and not an employee. Trainees cannot be taken as employees. Sweepers and Chowkidar drawing paltry sums per month and not borne on the regular staff sheet are to be excluded from the employment strength. Directors, working partners, managing partners, domestic servants and contractors are not employees. The onus of proving employment strength is on the establishment. Change in ownership is immaterial for the applicability of the Act. Composite factories come within the purview of section"
Hence, an employee has to be necessarily covered under PF, even if his salary exceeds Rs.6500/- per month.
Holder of PPF Account does not mean that he can be exempted from PF.
