TVöD contract E13 (limited contract 2 year) notice period
If you are aiming for a fixed date and are still on good terms with your boss, it is quite common to create an &quot;Aufhebungsvertrag&quot;, that is a contract in which you both agree to terminate your contract at a certain date, irrespective a of notice period. After all, you want to leave and your boss likely wants to hire someone new on your position.
You will likely get a call from the &quot;Personalrat&quot; though, as they want to check that you weren't somehow forced by your boss to contravene regulations this way.
