Actually, I work in a musty warehouse thats often overheated, and my work is so hard that the union contract specifies we get overtime after.....5 hours. No, not 8 hours...5 hours. Within the first hour my shirts are soaking wet with sweat. And that's just a warm-up.
Don't talk to me about hard work. Lift 250 packages an hour that weigh an average 20 pounds, do it for 5 hours a day--and did I mention our only break is 15 minutes w/ no lunch?--do that for about 8 weeks without missing a day, THEN talk.
