Why wait for the twilight of ones career? It seems the perfect answer for the author of this thread. I aim to be part time from my early 40s. My company has an 87% work option for 92% pay, this seems a really nice introduction to part time and will give me a little more time with my boy while he's still fairly young. What's 8% pay compared to time with loved ones? You can't take it with you guys!
