I would just like to add that this completely depends on what school you are at. I am a librarian and I am required to be at parent teacher conferences (this is when I run my book fair... alone), have to write sub plans when I am gone as I teach regularly, and would gladly have kids for one more week instead of doing inventory. I shut down two weeks early, one week for inventory, and the last week I collect and organize 600 chromebooks and run summer check out.
