Assuming you have one at all, what time do you have your daily stand up meeting? Are there reasons why you have it at that time? Do you like having it at that time?
09:00 at the start of the daily “Kernarbeitszeit”. I am not sure how to translate the term. A literal translation is “core working time”. Basically, my employer gives us the option to work between 06:00 to 18:00 with mandatory “presence” (working from home is possible) from 09:00 to 15:00.
