Discrimination in the workplace?
The Reg did a recent article on "losing your religion" on your CV. It's bad enough that you can be disciplined for wearing a cross in the workplace (and that case has cost BA a lot of money so far). Why be ashamed of your beliefs?
My own view is that you should be upfront about these things. I have put at the top of my CV that I was diagnosed with Asperger's Syndrome on the 1st April 2010 (in the afternoon, fortunately...). I've even been advised by recruitment agencies to take it off. I am convinced that I have been turned down for work because of it, but the fact is that if they don't understand what Asperger's Syndrome is they won't understand what benefits you would bring to the business. If they don't want me because I have a condition that affects the way I relate to staff, I can go and work elsewhere.
As for beliefs, if they have a bearing on how you do your work of course they should be on your CV.
I was recently dismissed from one company (those who were at the Register Live 2011 know who I mean) on the basis that I "would not fit in". They stuck by this even when they knew I had Asperger's Syndrome. I have a petition about this at johnairey.epetitions.net.
Yes, there are some people who view the discrimination regulations as an easy way to get money, however in my experience the tribunals are very difficult to persuade. They would rather believe that you are unemployable (for example, turning up to work when supposedly weren't meant to) than you have been discriminated against. A recent letter to the Guardian from a Employment Law solicitor pointed out that unreasonable claimants are the exception.
Fortunately I work for an understanding employer now (although it's further from home I'm now losing £2,200 per year). One of their HR staff described me as weird recently, which is spot on!
