Salaried Americans who work in an office… what are your typical work hours?

Last salaried job I had, I did 8am-4pm because I wanted to stagger to avoid the heaviest traffic. I mean, 6am-3pm would have been better, and I have had jobs with those hours. In the DC area, traffic really gets started at 7am and doesn't end until 10am, then again 11:30am-1pm for lunch rush, then about 3:30pm to about 7:30pm. That's both roads and bus/metrorail. The issue is that for every 5 minutes you're delayed getting out, it can add 10-15 minute to your total commute, depending on where you are. So if that meeting ran until 4:15, that's an extra 30 minutes to get home. I'd say my normal day was about 3-4 hours commute total, longer if the metrorail broke down, which about once a week. There were days I left at 4, and didn't get back home until past 8pm because of "single tracking." Basically, a day of work was get up early like 5:30-6:00 am, walk to bus stop, ride bus, get on metro, ride metro, walk to work, and hopefully get there before 8am. Then work until 4, and reverse the steps, get home like 6:30-sh (depending on metrorail and bus schedule timing). "Why didn't you drive?" Because it would take the same amount of time, really. At least I could cat nap and zone out on a bus or rail, and it cost slightly less when you add in gas, wear-and-tear, and parking fees. Plus, often work had a "compensation program" where my fare was deducted from my paycheck pre-tax, so I saved a little more money that way. So weekdays? Jack all gets done outside of work. Five days of just existing, no shopping, repairs, hobbies, or anything. You cram all that into the weekend. Now I work hourly from home, and the hell with commuting. It's brutal out here.
