I've been doing 8/80 for a while now, and I love it! I do 10 hour days MTRF, and I have my "week-mid" on Wednesday - it's amazing how much you can do on a Wed when everyone else is at work.
My manager and co-workers tend to respect my day off, with the occasional call, or need to switch my day off to another day. (Sometimes, if there is a holiday during the week, I'll switch my day off to coincide, so I get 4-day weekends). I would think how much you'd get bugged when your off would depend on how much your manager/co-workers respect your personal time in general
Some benefits to this kind of schedule:
- Your longer hours mean you're there when other people are not, so fewer distractions, more productivity
- If parking is bad where you work, and your new schedule means getting there earlier, you may not have as much of a problem
