“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?
All but one of my jobs (excluding hourly jobs as a teen) have been 9-5, the one that wasn’t was 9-6 with the justification that we had a 1 hour lunch in the middle… but like… I’ve taken a 1 hour lunch at every job… so I have no idea why that company was such a stickler for that. Basically no one did shit after like 4pm anyways
1 hour lunch means you are expected to leave the office (or at least not work). Some countries get really strict about a one hour lunch break where you don’t do any work and so it is carefully enforced there.
