Summary of the Judgment 1. Social policy – Male and female workers – Equal pay (Art. 141 EC; Council Directive 97/80) 2. Social policy – Male and female workers – Equal pay (Art. 141 EC; Council Directive 97/80) 1. Article 141 EC is to be interpreted as meaning that, where recourse to the criterion of length of service as a determinant of pay leads to disparities in pay, in respect of equal work or work of equal value, between the men and women to be included in the comparison, since, as a general rule, recourse to the criterion of length of service is appropriate to attain the legitimate objective of rewarding experience acquired which enables the worker to perform his duties better, the employer does not have to establish specifically that recourse to that criterion is appropriate to attain that objective as regards a particular job, unless the worker provides evidence capable of raising serious doubts in that regard. It is therefore for the employer to prove that that which is true as a general rule, namely that length of service goes hand in hand with experience and that experience enables the worker to perform his duties better, is also true as regards the job in question. (see paras 38, 40, operative part) 2. Article 141 EC is to be interpreted as meaning that, where recourse to the criterion of length of service as a determinant of pay leads to disparities in pay, in respect of equal work or work of equal value, between the men and women to be included in the comparison, where a job classification system based on an evaluation of the work to be carried out is used in determining pay, there is no need to show that an individual worker has acquired experience during the relevant period which has enabled him to perform his duties better. By contrast, the nature of the work to be carried out must be considered objectively. (see paras 39-40, operative part)
