What is up with these teachers?

They seem to think I'm Public Enemy #1 and out to get the students. Scheduling feels like a hostage negotiation. If anything deviates even slightly from their plan (+/-5 minutes), then tHe WoRlD iS eNdInG!!!! They seem to dislike not only me professionally, but me personally. It's super weird. *Obviously not all teachers, not even most, but enough that it's an issue. Some were rigid and could be adversarial before, but NOTHING like this.
