If your employer feels that they cannot accomodate you with any position which will accomodate you for your condition, it is important that you ask your employer to give this to you in writing then you can take this to your GP and prove thaat although you are able to walk with the aid of a stick, you are still unable to carry out your duties to which you are employed. Your GP will then be able to sign you off from work and put you in touch with a physio therapist in order to assist you with full rehabillitation. you will also be entitled then to make claims for benefits and you should go to your local job centre to discuss what you will be entitled to in order to support your living. I hope this helps you.
