Also worked in the NHS until I retired ,,,,,found it about the only place I had worked where there was no ageism (I was the same age as virtually all my colleagues !
there were however two incidences of ageism when I worked as a temp for a while after I moved from the South to the Midlands, before I found a permanent job ...one was in a computer firm, where there was a permanent job going, and as I would have taken anything the Human Resources dept gave me a pile of CV's to go through and to send out letters inviting people for interview ....she said DO NOT send appts to anyone over 25 !!!! Why, I said ...she said because I can't ask them to do the banking or run errands for the milk etc ...I said I wouldn't mind, its a job I want ....
Another incident, also in the Midlands ...I was working at another temp. job with the Finance Director and General Manager, who were looking for a permanent member of staff ...the FD asked me to apply as he was pleased with my work ...BUT the GM said No we are looking for someone younger (and more glamourous !) ...I subsequently bumped into another member of staff in town after I had left, who said they had had to employ THREE people to do the job I was doing as the young girl they employed had no idea how to use the computer (and she was younger than me !) No idea how to talk to clients on the phone and no idea of keeping the books to trial balance ........had to laugh !
