I'm not sure what kinds of opportunities will pop up for you, and I don't know how t he US system works, but my mum moved out of her classroom job a couple of years ago. She was a primary (elementary?) classroom teacher but switched to become a school librarian. She loves it, and she seems much happier now than she did as a regular teacher. She had to re-train but the department of education hired her before she was qualified and she studied part time as she worked for the first year.
