it's a tie. one was a job as a receptionist/scheduler for a photography studio. the boss, who was jewish, and used his real name with dark-haired customers and an alias with light-haired customers, noted that my surname is "overtly jewish" and asked me if i had ever considered changing it? when i said no he asked me IF i would please consider changing it! i was new in town and had just finally gotten this job, so i reluctantly agreed. first of all, i felt funny denying who i was (never mind that i am a jewish atheist; no one has an atheistic name lol!) second of all, the work was such that i had scheduled the photographer out for a month when they asked me to stop scheduling anymore, and i sat and twiddled my thumbs. each eight-hour day took a year. it was torment. this was on top of the realization that my employer's wife hired undocumented workers and underpaid them and screamed at them and treated them as slaves. i lasted a whole month there.

the other job was for an advertising agency, and i have written of this elsewhere, but they abused all their workers, not paying overtime for extra work (which practice was illegal in california, where i was) and had employees spying on one another as well. it was dreadful and i didn't last very long there either.

those were the worst, unless i am forgetting something.

The people make it good or bad. A self righteous Baptist ogre jerk off boss I had stands out

Production office in a plastics thermoforming plant. They made money hand over fist and clearly spent most of it paying OSHA to look the other way because visibility was literally six feet for all the particles in the air. No-one on the floor was issued respirators. They weren't even available. Even in the office it was miserable and I went home with a terrible headache every day of the year and a half I worked there.

When I was in my mid 20s I worked repossessing furniture and appliances. Day one, I sat for 2 hours in a truck with the guy who was training me outside a guy's house who had defaulted on his payments and refused to come out. I also went into several filthy houses to take their stuff while they watched and asked me not to. I quit, like, 30 mins into my shift the next day. I knew I was going to quit after the first day. I don't know why I even bothered to come in for those 30 mins the next.

I worked in a dry cleaner. It was gross - handling people’s dirty clothes all day. It was 100 degrees in the summer. And a segment of the customers treated you like a piece of shit because you’re just the peon who cleans their clothes.
Also - “dry clean” - is neither dry NOR clean!
