I have a "part-time" interview on Friday! I work full time now as an IT Project Director, but Im exploring ways to switch to Part Time. Im pretty close to FIRE, so I reached out to old bosses, colleagues, etc. and asked if anyone was looking for an experienced IT PM to do some part-time or short term contract work. I got a few bites.
I've worked part time in the past when kids were young, and during market downturns. The thing is that I really kind of like to get dressed up, go to the office, talk with lots of people, and work on challenging problems....just not ALL DAY EVERY DAY!
I know several IT folks who have "retired" from a full time job to doing the same work but with less hours, more vacation time (unpaid but who cares) flexibility and freedom.
If you really LIKE what you do I think its the best plan.
