Yes, I am working. I am 52. I took a few years off when my kids were born, but went back P/T almost right away.
Luckily, I got my MSN pretty early, and got into leadership.
I am currently a director of the med/surg division in a local community hospital, and I love my job. I don't think I could still work at the bedside, and certainly not 12 hour shifts, which everything seems to be now!
