I generally enjoy my job (underground mine support/backfill/construction). Most of the time though I'm just sitting around with nothing to do, but have to show up anyway because who could imagine a world where (at least) 40 hours of your life isn't given to a company. Hell, yesterday I was legitimately bummed out that it was the end of shift and I didn't have time to see a project through to completion. I would have loved to finish it just for the personal satisfaction of a job well done. Capitalism is pretty efficient at sucking the joy out of workers who enjoy labor. I'm sure this is more common in salt-of-the-earth physical labor type jobs.
