An EU court ruled that offices can limit the wearing of religious symbols by the staff, in order to maintain an air of religious neutrality. I think that is a reasonable policy.

The court decision tried to allow some flexibility but block arbitrary discrimination, but I think it did not entirely succeed at the latter.

To close the door on arbitrary bias, the court's decision should have included a requirement that any distinctions made between some religious symbols and others must give equal treatment to all symbols that are equal as regards how prominent and visible they are.

It makes sense to distinguish between large religious symbols that everyone in the office can't help noticing and tiny ones that might even be under a garment. Thus, it is legitimate to regulate religious headgear more strictly than pendants or bracelets. But the law should require that all kinds of religious headgear be treated alike, regardless of which religion they represent.

A veil is a different kind of issue. Inside an office, it is reasonable to require that the staff show their faces. However, for a government to require people on the street to expose their faces to facial recognition cameras is a step along the path that leads to Chinese-style repression.

The right to cover one's face in public should be a human right for everyone.
