Do you have to remove your hat for a Drug Test?

The short answer is the employee is not required to remove their hat if it is worn for religious purposes, unless the collector observes something unusual, in which case the employee must remove their hat.    

When an employee is asked to remove his or her hat or head covering, and refuses to do so based on religious practice, the collector may exempt the employee from removal of the head covering, unless the collector has an observable indicator that the employee is attempting to hide inside the head covering adulterants or other substances which may be used in an attempt to adulterate or substitute a specimen.
