Getting turned down for work with a chronic back problem

Hello @Rayofhope and a warm - if rather belated - welcome to the community. We are glad to have you, but seem to have been short of bodies to answer posts today. Really very sorry about that, and that you've been kept waiting.
Heartfelt congratulations on your retraining - it cannot have been easy.
There may well be others here in a similar situation to yourself but it might take a little while for your post to filter through to them, so please bear with us. In the meantime you might like to have a look at our 'Ask an Employment Advisor' thread. Have a look at the conversations and please, if you feel you can, join in.
Must get this sent to you, so I will sign off, but please, please, please do not hesitate to be in touch to ask us any questions or to tell us anything more about yourself.
Here and listening,
Warmest best wishes,
Richard
PS You might also find some friends in the 'Dealing with chronic pain' thread.

Hi @Rayofhope
If you have been away from the job market for a little while, it can be useful to start with some volunteering as @Lasian_Scope says.

If you are already job searching independently, we might be able to help you improve your job hunt with Scope's Support to Work, info here:

What kind of office jobs are you applying for?
