You should listen to some music op, it will keep you stain alive.

OML

Realistically, it's OP that needs to tell his boss to piss off after this ordeal.

#3, my thoughts exactly.

Actually, that's exactly what you're being paid to do.

They're probably getting it in sellable condition, which means that is literally what he gets paid for.

Actually, OP can refuse because it is a health violation and he wasn't given proper equipment to deal with it. Cleaning that much piss isn't what construction workers, etc get paid to do. He had someone else's piss on him. If my bf had been forced to do that without proper equipment when he was working in construction, I would have been angry.

Thank you number #20

Down a drain outside, I expect.

I was about to suggest that or a boat pump.

I think a boat pump would be better than a shop-vac. Either way you're sucking up piss and sometimes that can spray about.

Where did this piss even come from? Other workers? That's quite a bit of piss for one person...was it there before they started working?
