COMMENTARY FROM ARTHUR BRAUN | The Court of Justice of the European Union recently published a decision in proceedings on a preliminary issue, stating that EU member states must require employers to record all employee working hours (C-55/18). This case involved a suit filed by a Spanish union organization in the banking industry, not exactly the traditional players in unions fighting against exploitation of the working classes. This decision did not receive wide publicity in the Czech Republic, but in Germany and elsewhere in Europe it did.
