GRP Rainer Lawyers and Tax Advisors in Cologne, Berlin, Bonn, Dusseldorf, Frankfurt, Hamburg, Munich, Stuttgart and London - http://www.grprainer.com/en conclude: An employee initially sued for payment of overtime before the Kaiserslautern Labour Court and then before the Mainz Regional Labour Court (LAG) (Az.: 5 Sa 257/13), however both Courts dismissed the claim. The plaintiff, an employed lawyer, argued that he had to work longer than contractually agreed on the cases assigned to him. The employer countered, on the one hand, that it was not aware of the extra work and, on the other hand, that the extra work had not been recognizable.
