True or False: Watchmen may be assigned additional job-related duties while functioning as a watchman.

The statement that watchmen may not be assigned additional job-related duties while functioning as a watchman is correct. This designation comes from safety and regulatory practices that prioritize the watchman's primary responsibility, which typically involves monitoring and ensuring safety at specific locations. Allowing additional duties could distract from this essential function, potentially leading to safety incidents. Thus, the integrity of the watchman's primary role is preserved, and their focus is maintained on the critical tasks at hand. This practice helps uphold safety standards and reduces the risk of accidents in an operational environment.
