“The 9[am] to 5[pm]” is a common term for one’s regular job, on the basis that normal people start work at 09:00 and finish at 17:00. I’ve worked a few jobs and closest I’ve ever gotten to this is 08:00 to 17:00, which I gather is standard.
Are there real jobs where people actually start at 9 and finish at 5?
No. Companies have stolen 2 extra hours from us. They used to include a paid lunch hour in those 8 hours. Now, it’s not only 8-5, but we don’t get paid for the lunch hour.
