Worst job: I had a brief stint last year working at a brand new university that had just opened up - teaching ESL or English as a second language. Everyone I worked with, with the exception of three other ESL teachers, were insane. Literally. Because as I later found out, this wasn't a university, it was a religious cult using the university as a guise to recruit new followers into their religion.
Creepiness aside though, working in that environment was a lot like what I would imagine fighting in a warzone would be like. The psychological attacks and abuse from the cult members were tremendous and relentless when they saw I wasn't interested in them or their religion. They were highly suspicious. What made it doubly worse was that they also provided housing for me and the other teachers, and given their behavior upfront, we all felt paranoid about both our safety and whether or not there were hidden cameras in our rooms, watching our every move. Though I'm normally the kind of person who can stay calm under a lot of pressure and stress, I lost my cool for the first time in a work environment over a dispute about cafeteria access that had escalated over the course of two weeks. I was yelling and screaming so hard that I seriously, if not permanently, damaged a specific range in my voice (which sucks, because I used to sing a lot while I was in college).
I left after three months. I had a bad feeling right from the beginning, and if I weren't so desperate for money, I would never have taken the job. I only just recently stopped having nightmares and traumatic flashbacks about it.
Best Job: When I was in high school I worked for a local landscaping company for one summer. Loved it. Got to be outside, fresh air, exercise, and the physical labor has a way of allowing me to leave my brain for once - which is always a good thing. But most of all, the people I worked with were wonderful. I also worked at my uncle's vegetable farm this summer, too, and I enjoyed that as well for the same reasons.
