Stop leaving your classroom full of things you don’t want

I got hired at a new school and the teacher before me had been in this room for 10 years. Well the teacher got an instructional coaching position and left all of their unwanted crap in every single cabinet. There’s not a single empty cabinet for me to put my things in. I’m an experienced teacher, so I already have a bunch of my own stuff, meaning I now have to completely clean out all of their stuff before I can even put my own crap away. I’m sick of teachers doing this. It’s a common thing in the education world (at least from my experience) and admin needs to start making sure teachers completely clean out rooms before leaving. I understand that there might be a lot of useful stuff, but put it in boxes in the hallway, don’t leave your mess in the classroom for the next teacher to clean up. It’s hours of added work on top of the stress of having to organize my own stuff and set up a new room with limited time and it’s not my job to clean up the mess of another teacher. Rant over.
