At issue was a challenge to a German statute requiring employers to pay up to six weeks of annual sick leave for employees who worked more than ten hours per week, or more than forty-five hours per month. R-K sued her employer, an office cleaning company for whom she worked ten hours per week, after her request for eight hours of sick pay had been refused. Her claim was that, if Article 141 covered statutory-mandate sick pay provisions, the German legislation discriminated indirectly against women. The ECJ held that Article 141 covered sick pay, and that consequently the statute “must, in principle, be regarded as contrary to the aims of Art.”, unless the German government could muster an argument to the contrary. The Court rejected the government’s submission that compared to full-time workers, part-timers “were not as integrated in, or as dependent on, the undertaking employing them”, declaring that “these considerations, in so far as they are only generalizations about certain categories of workers, do not enable criteria which are both objective and unrelated to any discrimination on grounds of sex to be identified.” It then announced a variation of the least-means proportionality test developed in Bilka. To mount a successful defense, Member States must convince a judge that the legislative “means chosen meet a necessary aim of its social policy,” and that these means “are suitable and requisite for attaining that aim.” The national judge has a duty to apply this test. The Court thus extended the Bilka framework to the judicial review of statutory-mandate social policy.
