I have never really hated any job that I had - I always managed to find the work interesting no matter what I did.

It was always the people around me, mainly co-workers, that would make the job unpleasant. Someone on a power trip, someone who didn't do their job and others would have to make up for it, co-workers who would try to sabatoge the work that you did to make themselves look better, etc.

I was between jobs a few years back and decided to try and give it a whirl at using my formal education to help others. Took a job as a grief counselor at a local cemetary. It actually ended up being a salesman for pre-need and at-need cemetary services. Worst thing is that is was full commission. While I loved helping folks at their time of need, I hated the fact that I was actually selling them something they didn't want right then but knew they had to have. I lasted about 3 months and knew I had to find some other way to use my experience.

My advice - plan ahead so you don't have to make such an important decision at the worst possible moment in your life for your loved ones.

A temp job one year over Christmas at a contract packager. I packaged powdered Easter Egg dye. Turned color on contact with water. Go to the bathroom, come back with purple hands. Or if any dust got on your face etc.. I'd also sneeze colors for days. That's my favorite worst job.

Same place..had to screw caps on bottles to a certain torque.. Hurt the hands after awhile.

Different place, temp work...had to use a table saw to saw chips in records (old vinyl ones) so they could be disposed of. Did that for weeks.
