What discrimination?

Looks like the European courts have junked all but one of the recent religious discrimination appeals although the one upheld was certainly the case that made the least practical sense. The ECHR upheld the appeal of Nadia Eweida who back in 2006 had a job as a check-in clerk for BA and was told not to wear a piece of jewellery which happened to be a cross on a necklace. At the time BA had a very strict policy on jewellery (which I can sort of understand for public facing roles) regardless of the religious significance or otherwise. The BA rules have since changed (2007) and interestingly Nadia still works there, so I guess she forgave them. In any case I'm not sure where it says that Christians must wear crosses, I always thought fishes were the approved symbol, then again, I'm no theologian. Perhaps one of my religious readers could point me to the verse that says "And Jesus said, take this rather delicate and attractive 9 carat necklace and wear it in remembrance of me...and perhaps a nice little brooch sometimes too"?
