In our next school-block, our class will be split in 2 groups, one goes to school during the first week, the other during the second week.
Sounds reasonable and all until you recognize, that the first week only has 3 schooldays, because of a holiday and a vacation day.
The holiday is set by law, so you can't actually do anything about it, but the vacation day can be set freely.
That means they could have just moved the vacation into the lockdown, but choose not to, because fuck students.
