Art. 119 EEC

Each Member State shall in the course of the first stage ensure and subsequently maintain the application of the principle of equal remuneration for equal work as between men and women workers.

For the purposes of this Article, remuneration shall mean the ordinary basic or minimum wage or salary and any additional emoluments whatsoever payable directly or indirectly, whether in cash or in kind, by the employer to the worker and arising out of the workers’ employment.

Equal remuneration without discrimination based on sex means:

(a) that remuneration for the same work at piece-rates shall be calculated on the basis of the same unit of measurement; and
(b) that remuneration for work at time-rates shall be the same for the same job.
