I was getting overworked, every other branch of this old company had two people doing the job I was doing. I had a system to get most of my work done except some I would finish the next morning before the next day's work arrived. Instead of asking me in person what I was doing my boss finished my work that afternoon after I left then covered my keyboard in paperwork and left a post it note on my screen saying essentially "wtf is this?"

It was very unprofessional and I quit after I got a job with a bigger company with a 40% pay bump where I now contact my old boss to tell her that I need her to do tasks for my new company.
