Yeah that's exactly what did in a 5 yr "bridge " approach from Ft work to full retirement.
Worked Only Tues, Wed and half day on Thurs ,strictly during the 30 week academic calendar
Added bonus I w was working for myself,not the college
I had a partner and the college joffered us the office space and the overhead.
We gave them a share of our bottom line and also established Endowed Scholarships .
The college also made coin from food service rev.and dorm rev from our in residence seminar series for executives from business, industry and the health professions.
We did 15- 20 (3 day sessions) a yr, each with 40-50 professionals. The money was great, approx 2 and half times what my former salary was
Was a win win and a helluva transition to just ramp down and slide into real retirement and we skied our asses off Mon and Thurs and Friday
I was very fortunate because I could draw my pension and got my health insurance so it was a very sweet deal.
I GOT a life
