If you are the kind of person who likes to look things up, beware. There is no Labor Code in Germany. Instead, employment law is regulated in a bulk of statutes, collective agreements ,and standard company agreements. Case law and academic opinions, so called “ruling opinions or ruling case law ('herrschende Meinung' or 'ständige Rechtsprechung')”, play a vital role here. If you have been fired, it is a great help to contact a lawyer if you want a severance payment. But again, remember that you have to pay the lawyer yourself, no matter who wins – in the first instance. Your legal insurance will usually cover the costs for this dispute.
