she's 65.
how much longer do u want her work?
how much longer does she want to work?
her retirement package is probably pretty good, being there 35 years when the package was good, and why not take it & enjoy it!!
as far as others not staying, maybe its the structured pay? benefits? i am sure its not as good as the "old guard".
Happy Trails to her!!!! (if that is what's happening)
