This is dreadful Ally, I assume your company are NOT medical experts?
The document I sent you was enough on its own, to explain exactly what Fibromyalgia is, and how it affects people in different ways. If they sack you, then you could take your case much further.
Like I say to everyone "never back down when you're in the right!" - They obviously do not know what or how you cope on a daily basis, otherwise what was on the information on your PIP Award Application form was indeed correct when it comes to a person dealing with Fibromyalgia on a daily basis!
All doctors have access to the BMA (British Medical Association) and have paperback copies of the (BMJ) British Medical Journal, also available online.
We even have our own documents on here, which maybe worth pointing out to people, that need to reference about the condition, even doctors use this site for various articles, so it must be kept up to date at all times. The address is:
https://patient.info/health/fibromyalgia-leaflet
That tells anyone what your condition entails in detail, which you cannot just brush under the carpet. If your employer contacts the DWP about PIP, the employer will be told it is a 'non-means tested' allowance, which baiscally means it can be paid to a person that is working.
You, yourself could take this further - I personally, would take it further, but I am not you. But really, you need to know where you stand with this so-called company, with no respect to it's employees. Once, you know this then you can start planning your next move.
Claiming PIP while working is not "Benefit Fraud" - if your company knew the whole facts then they would have known this. Everything, they have put you through, you could easily throw back in their faces, "they would not have a leg to stand on!"
It sounds like they are putting across to you that they are professional doctors, they aren't, they are well out of line though, and if taken further you could claim compensation against them, if I am correct.
I would like to see where they go with this next, contacting the DWP regarding an employee would be in breach of the Data Protection Act.
Ally, you have enough ammunition to take your case further, whether they are brave enough to do so, is another matter. But from what you put, they would certainly be in the wrong.
@Dimples, your message is right to the point, staying strong Ally is the hardest part, try not to let this get you down. I know it may sound easy for me to say, but to be honest, we all at some point in our lives have bad times, even I have had plenty - but I held my head high and let your employer struggle, if or when you take further action. Everything I have put in this message is pointers you can use against them.
It is probably not an easy time right now, even with your illness but pull yourself together at your own pace, go back to ACAS and CAB, and put everything on the table. I wish you all the best for now though.
Regards,
Les.
