Every day these guys would show up at 8am and long sleeves and jeans and hard hats, work super hard, pee in a port-a-potty, and be exhausted by the end of the day. They worked out in the 100 degree heat as well as the rain as the job got near the end. Luckily the bosses were pretty cool and provided them with decent food for lunch and plenty of drinks (but I still offered them food and drinks too).
I on the other hand was working at my desk in my air conditioned house in comfortable clothes. A few times a day I'd put on my flip-flops and wander around outside to check on their work, ask a few questions, and then head back in when it got too hot.
And a couple of times the plumbing sprung a leak just as they were getting ready to leave, despite their best efforts to get all the risky work done early, and they they had to stay super late. Once the plumber was here till midnight after arriving at 8am.
I used to have thoughts about how it would be nice to have a job with totally spelled out requirements that end at 5pm and then you have the rest of the day off. But no more. I'd much rather work at my comfy desk inside and deal with the occasional call at 9pm on a Saturday than deal with what they all went through.
