Formally, Hannah has to agree on your Urlaub (and she anyway has to sign your Urlaubskarte). But in most cases, you don't have to ask Hannah explicitly when you want to take Urlaub. If none of the items in the following checklist is problematic, you can assume that she agrees. If there is a major update of this checklist, you will be informed by mail. So you don't have to go to this page every time to check that nothing has changed.

1. Check that your Urlaub does not conflict with any teaching duties

2. Check that your Urlaub does not conflict with the corrections of exams (important special case of 1)

3. Check that your Urlaub does not conflict with any important deadlines (e.g., a submission deadline)

4. Make sure you enter your Urlaub in the AD calendar

5. When you are in doubt, ask Hannah, but you usually don't have to

6. When you want to take Urlaub for an unusually long time at a stretch (a month or more), better do ask.
