I have a friend who is interested in quitting his full-time job in Germany. He has been working for a little over 1 year at 40 hours per week. How much notice must he give to his boss when he quits?
The work contract doesn't specify how much notice must be given, merely saying that the normal for Germany applies. His boss has verbally told him that he should say 3 months in advance.
As we are in Germany I assume that notice to quit must be in writing, but are there some other details that he should be aware of?
