This is one of the many benefits of working in healthcare. My wife had ~ 7 years experience working in OB/GYN, decided she wanted off the floors and to go part-time after having our kids. She now works Thursday and Friday (no holidays or weekends) as an advice nurse in an outpatient OB/GYN office, teaches two classes per week, maybe gives an injection or two but mostly time on the phone. She makes $65/hr and is eligible for free healthcare for the entire family, though we're covered under my similar plan. If you live within 2-3 hours of the Bay Area and benefit from their pay scale and the strong healthcare unions, you can do very well. RTs and physical, occupational and speech therapist are always in demand. I know a ton of med/surg and other hospital RNs that make even more (well >$70/hr) and choose to work part-time because they have:
1. union protection
2. free or greatly reduced healthcare
Sounds great. All this harping about "innovation" in other fields is great - till someone finds a more innovative replacement for you.
