In October 2006, Nadia Eweida, a Christian employee of British Airways, was asked to cover up a cross necklace which depicted a Christian cross, and was placed on unpaid leave when she refused either to do so or to accept a position where she did not have to cover it up. She was wearing the necklace on the outside of her uniform, contravening BA's uniform policy for jewellery. Eweida planned to sue the airline for religious discrimination. Some Christian groups accused British Airways of double standards, as Sikh and Muslim employees are not prevented from wearing religious garments at work, since these are impractical to cover up. Although the wearing of garments is a requirement in some faiths, in this case, British Airways believes that wearing a cross is not necessary in Christianity, in general.
