The Spanish trade union federation, Federacion de Servicios de Comisiones Obreras (CCOO) brought a claim against Deutsche Bank for infringement of the WTD, challenging the lack of any system for recording bank workers’ daily working time. The union argued that a recording system was needed to fulfil the bank’s duty to take all necessary measures to ensure workers’ rights to minimum daily and weekly rest and rest breaks are honoured. The Spanish court referred the case to the ECJ.
