While cross-wearing BA employee Nadia Eweida enjoyed victory at the European Court of Human Rights (ECHR), three other Christians lost their cases, including hospital nurse Shirley Chaplin, who had been prevented from wearing a cross visibly around her neck.
They will be appealing today's judgment at the ECHR's Grand Chamber.
Speaking at a news conference in central London, Ms Chaplin said she was "very disappointed" by the judgment but heartened that other Christians can now wear a cross in the workplace.
She said she still feels that other religions are given more freedom in the workplace and called upon David Cameron to live up to a promise to change the law to protect cross-wearers.
