Civil servants are expected to stay neutral with respect to politics or religion when they discharge their duties. More generally, they are expected to keep a certain reserve and not make comments or demonstrations that may be interpreted as political, religious, or other bias in the course of their duties or as an endorsement of particular religious or partisan political views by the government. Teaching personnel in government-operated schools must not, by law, endorse any political or religious point of view; they may also face sanctions for wearing overt religious symbols.
