Lisa I for one totally understand where you are coming from. I worked for the NHS for over 15 years and when offered my job, undertook the required Medical, where I informed them of my IIH. Granted at the time I was being treated with Diamox and the odd lumbar puncture, so my symptoms were manageable. Once employed I found them quite understanding, however, when I had to have my first shunt as I was told I was going blind, they were less than understanding. In order to return to work after my surgery, I had to have a computer which would allow for a larger font, a chair and other things to enable me to work, as I was left partially sighted with tunnel vision and had mobility impairment and back problems due to the LP shunt, but the department I was on did not have them in place when I returned to work, despite Access to Work advising them and constant reminders.
When I returned to work I was shunned by my colleagues and things were made difficult for me so I asked to be transferred to another hospital in the trust. I was placed on secondment for 3 months and in essence had to fight to keep my employment. As I was a Unison steward I went to my union and asked for their help, and eventually was employed by the Infectious Disease department. I continued to work and even attained promotion, which meant I was then leased to a Hep C Study Group as a Data Manager, but then when I needed revision surgery my contract was terminated, and they again told me I was to be put on secondment. They gave the reason as the funding had run out for my position with the Study Group, but my boss had actually told me it was because of the surgery. When the trust failed me yet again by not finding me an adequate post but insisted on secondment, which means basically if you can not find another position within the hospital in 3 months, you're contract is terminated, (I had to fight the first time) I decided that despite my career with the NHS, I would be better off elsewhere, so I took legal advice, went to an Employment Tribunal for disability discrimination. I had no solicitor but my husband and I handled it ourselves. Their solicitor kept sending me threatening letters saying I could not possibly win but I stuck in. I had plenty of evidence, and my Neurosurgeon and Neurologist wrote letters on my behalf, and in the end I won. I then was advised by my Neurosurgeon to take my NHS pension on medical health grounds which I did.
So my advice to you would be to contact ACAS, and your union if you're in one, and if you have any written evidence etc. bundle it together in case you do decide to go to the Employment Tribunal. Don't give in without a fight and don't go to a meeting without a representative from your union if you're in one, if you don't have one ask ACAS to advise, but delay the meeting until you have found out what your legal position is first.
Whatever I or the Foundation can do to help you we will, as we are advocates for you, and will do all we can.
