Have you worked in factories? How was it?

I’m in a very transitional period of my life right now, no job and I have dropped out of uni. Got my diagnosis about 2 weeks ago. We’ve been discussing the idea of me going go work and the idea of factory jobs was brought up by her. Now i had a guttural negative reaction to it, but maybe it wouldn’t be so bad? Not doing it for the rest of my life obviously, but it doesn’t sound too bad. Have you got any experience with a job like that?
