What is a "normal" work week?

[214Chevy]

I'm a firefighter and I work in 24 hour increments. So, I'm easily pushed to or past the 60 hour work week if I work 2-3 days a week. But hey, I got the only job in America where you won't get fired for sleeping on the job. As long as that bell doesn't ring, we are at the station chilling..."sittin on our nuts" as we like to call it.
