On 13 September 2022, the German Federal Labor Court (Bundesarbeitsgericht, BAG) clarified in a highly regarded decision (1 ABR 22121) that employers are legally obligated to maintain a system in their companies by which the working time of employees can be monitored and recorded. So far, only the press release of the BAG is available. A final evaluation and classification of the decision will only be possible after publication of the reasons for the decision.
