A poll to see which set of hours is more common. If neither, feel free to explain in a post.
I work 8:30 to 5:30. I don’t get paid for lunch (but I have to take one. By law. Stupid state of California looking out for my own health and making me work late!)
I could probably work 8:30 to 5:00, but I work close enough to home that if I take the full hour I can go home at lunch for a bit and relax.
7:00 to 3:30.
What, no 10 to 6?
That’s what I usually work.
I said 8-4, although it’s really more like 8:30 to 4:30.
I’ve always worked 8 to 5, which is 8 hours of work and 1 for lunch. or 8:30 to 5:30, but those aren’t in the options in the poll.
7:30 to 4 generally, unless my boss is in the office. Then it’s 7 to 5 or later.
Roughly 7-5, but usually longer.
8 to 5 is “working hours”
Honestly though, I work anything from 7:00 am to 9:00 pm or from 9:00am to 4:00 pm depending on what is going on that day and how many calls overseas I have.
7:30 to 4. Lunch is unpaid.
Whenever I want, as long as I’m in no later than 9:30 and put in 8 hours.
0830 to 1700. Get (unpaid)1/2 hour for lunch but we take an hour, so I guess I’m getting a 1/2 hour for free.
9-5:30. Except once a week I work 1-9 and every third weekend I work 9-6 on Saturday and 1:45-6 on Sunday. If I work the weekend I have Friday off and a half day the following Tuesday.
I am beyond incensed that you didn’t have my option there. 
8 to 5 with an hour lunch, or 8:30 to 5 with a half hour lunch. (unpaid lunch) Just depends if I can/feel like sleeping in a little. Could do pretty much anything from 6-3 to 9-6, my boss is pretty laid back about that kind of stuff.
9-6 on early days, but 11-9 is much more common. Unpaid lunch/dinner hour is built in.
At the summer job I’ve had the past few years, between 8 and 8:30, traffic depending, to between 5 and 5:30 (or whenever the KLM flight lands in Montreal, whichever comes sooner). I rolled my lunch and breaks into a longer lunch “hour”.
Working near the runway was useful. Swissair usually indicated that it was nearly time to go to meetings.
I work from about 8:15 till anywhere from 5:00 to 8:00 depending on my caseload. I usually leave between 5:30 and 6:00, though.
My work hours are 7:40 to 3:05. But I’m usually on campus from 6:30 until 3:30 or so.
Tax lawyers have pretty sweet hours (compared to other big-firm lawyers). I typically work 8 to 6 (or 7 or 8 depending), and answer emails all night from the deal guys, and go to the office on Sunday morning like once or twice a month.
7-4 with an unpaid hour lunch and two paid 15 minute breaks. My commute is much nicer than when I previously worked 8-5 and my department was still in our old building further away on a busier highway.
