We have a new nurse on our unit. A sixty year old white haired RN. She probably wouldn't have been hired at a major metropolitan hospital, but she fits in nicely at our small rural hospital. I asked her if she had trouble finding a job at 60, (I'm 63) and she said no. However, the only places that called her back were the ones that offered fewer benefits and lesser pay. The smaller ones like where we are.
Ageism is alive and well in nursing, just as it is in most professions. My 60 year old new colleague didn't get her first, second, or third pick, but she got a job.
