A morality clause is a term within a contract of employment that prevents the employee from behaviour that could bring the employer into disrepute, or is contrary to the ethos of the employer.
The morality clause typically allows for the employer to take disciplinary action, up to and including the termination of employment, against the employee if the clause is breached. Morality clauses are sometimes seen in high-profile positions, such as in the entertainment industry, or in religious institutions.
