The court found that there had been a violation of religious freedom in the case involving a British Airways employee who was barred from visibly wearing a Christian cross around her neck while at work. However, in the second case involving a nurse in the geriatric ward of a British hospital, the court found that the protection of health and safety on a hospital ward justified her employer’s prohibition on wearing a visible cross necklace.
A recent study by the Pew Research Center's Forum on Religion & Public Life found that regulations on the wearing of religious symbols increased globally between mid-2007 and mid-2010. In mid-2010, religious attire and other symbols were regulated in 57 countries (29%), up from 21 countries (11%) in mid-2007. Regulations increased in places as diverse as France, where the burqa was banned, and Rwanda, where the government prohibited religious headgear in photos for government documents.
