Health and safety at work – Organisation of working time. Articles 3, 5 and 6 of Directive (EC) 2003/88, read in the light of art 31(2) of the Charter of Fundamental Rights of the European Union, and arts 4(1), 11(3) and 16(3) of Council Directive (EEC) 89/391 should be interpreted as precluding a law of a member state that, according to the interpretation given to it in national caselaw, did not require employers to set up a system enabling the duration of time worked each day by each worker to be measured. The Grand Chamber of the Court of Justice of the European Union so held in a preliminary ruling in proceedings concerning the lack of a system for recording the time worked each day by the workers employed by Deutsche Bank SAE.
