Guys partying on the clock at Chrysler...

20 years in a "small" factory. 40 guys on floor during the day.
Pay day, Thursday, most hit the bank, then the bar, then back to work after "lunch". Had a couple of very good men in the shop that started the day, every day, by getting high before 7am, then at 11:30 again during lunch.
A lot of productivity in the '80's in the shop courtesy of "crank"(meth?).
I can't imagine any of of this is uncommon, at the same time though, in this day and age, I can't imagine it would be tolerated either.
