Nohad Halawi, who worked at Heathrow Airport, is suing her former employers for unfair dismissal, claiming that she and other Christian staff at the airport were victims of systematic harassment because of their religion.
She claims that she was told that she would go to Hell for her religion, that Jews were responsible for the September 11th terror attacks, and that a friend was reduced to tears having been bullied for wearing a cross.
Mrs Halawi, who came to Britain from Lebanon in 1977, worked in the duty-free section as a perfume saleswoman of the airport for 13 years but was dismissed in July.
Her case is being supported by the Christian Legal Centre, who say it raises important legal issues and also questions over whether Muslims and Christians are treated differently by employers.
It comes amid growing concern among some Christians that their faith is being marginalised and follows calls from Lord Carey, the former Archbishop of Canterbury, for Christians to be given greater legal protection in the wake of a series of cases where they have been disciplined or dismissed for practising their faith.
