"Telecommuting" in academia
Doing it part-time is rather common at least in places i have worked. At moment me and most of my colleagues work from home two days of the week (usually Mondays and Fridays for most and Thursdays and Fridays for some) on the days that no teaching is involved. If there is an important meeting we will show up otherwise we skype. I think i generally work on average 6.5 days in a 22 day work month from home.
