i was in the exact same position as your friend. i too used to be a nurse, but due to my lack of mobility i had to stop doing that. I did the admin for my team for a while, but that wasn't sustainable seeing as that was top of a band six, whereas the admin job was a band 2.
Anyway, in conjunction with occupational health, it was decided as i couldnt carry out my duties as a nurse even with adaptations, i would have to go on the redeployment register. this is when you are "at risk" so any jobs that come up that you fit the JD you are garunteed an interview for. I didnt find out till after but where i worked you only had 3 months on the redeployment register till you got made redundant.
So yes, your friend could lose her job if they dont have anything suitable for her. they cant be expected to make something up for her that they dont need - after all its our money thats paying her wages. The onus is still on her to be the sccessful candidate for any job she is put forward for interview for, not cushty slotting her in beause she cant do the job she is supposed to do. All this is perfectly legal and probably will happen unless she fnds something
Anyway, i have 2 bits of advice for your friend
1) She must continue looking for jobs herself. the people that do the redeployment were useless at my end, because even thought they had my cv they didnt really understand what sort of things i COULD do. i saw the job i'm currently in (in the same PCT), interviewed and got it off my own back. The redeployment people hant even matched me to it, or seen it as something i could do.
2) don't panic. I was devastated that i could no longer be a nurse but to be honest, i like my ne job much better, less stress and responsibility, same money, better for my health
