An institution, employer, or authority attempts to prevent someone from practising their religion.
An institution that claims to be neutral but specifically bans religious practice is not neutral — it is hostile to religion. True institutional neutrality accommodates religious practice where it does not unreasonably disrupt operations. A blanket ban on all religious expression — prayer, dress, or observance — imposes a secularist position as the default, which is itself not neutral. The law in many jurisdictions protects religious freedom, including its outward practice, and requires accommodation of religious observance where reasonably possible.
