What's the worst job you've ever had?

working at a hotel with a couple of the worse managers in the history of Hospitality. That was by far the worse job and I once spent half a year working for my uncle at a couple recycling plants in Texas and Central Florida. Basically working in trash and that was still a much better experience than working with those two pieces of crap.

Lots of them were bad.
Steam cleaning an industrial lathe. - Imagine being dressed in waterproofs head to toe; big steam cleaner on your back; heavy 'gun' type instrument you have to hold and then firing water/steam at 130*C at quite some pressure while you clean this piece of machinery that was encrusted with grease, oil, grit and those shitty metal burrs that come off the metal being machined.

Used to go home stinking of sweat; oil; grease and then spend half an hour in the shower trying to get little bits of metal out from under my fingernails.
