Section 4 — Duty of employer to pay equal remuneration to men and women workers for same work or work of a similar nature.

4. Duty of employer to pay equal remuneration to men and women workers for same work or 

work of a similar nature.—(1) No employer shall pay to any worker, employed by him in an 

establishment or employment, remuneration, whether payable in cash or in kind, at rates less favourable 

than those at which remuneration is paid by him to the workers of the opposite sex in such establishment 

or employment for performing the same work or work of a similar nature. 

(2) No employer shall, for the purpose of complying with the provisions of sub-section (1), reduce the 

rate of remuneration of any worker. 

(3) Where, in an establishment or employment, the rates of remuneration payable before the 

commencement of this Act for men and women workers for the same work or work of a similar nature are 

different only on the ground of sex, then the higher (in cases where there are only two rates), or, as the 

case may be, the highest (in cases where there are more than two rates), of such rates shall be the rate at 

which remuneration shall be payable, on and from such commencement, to such men and women 

workers: 

Provided that nothing in this sub-section shall be deemed to entitle a worker to the revision of the rate 

of remuneration payable to him or her with reference to the service rendered by him or her before the 

commencement of this Act.
