Under what conditions can an employer legally restrict employees' religious practices at work?

An employer is legally permitted to restrict employees' religious practices at work when such practices create an unsafe work environment. This is grounded in the obligation to maintain workplace safety for all employees and to protect the health and well-being of both the individual practicing their religion and their coworkers. For instance, if a religious practice involves a safety hazard, such as wearing certain types of clothing that could pose a risk when operating machinery, the employer has the right to impose restrictions to ensure the safety of all individuals in the workplace.

In contrast, options involving special grooming requirements, disagreements with beliefs, or recognition of holidays do not provide a valid legal basis for restricting religious practices, as these factors can often be accommodated without compromising safety or the rights of others. The focus on safety allows for a balance between respecting religious freedom and ensuring a secure working environment.
