What term refers to any person performing operations for a licensee, regardless of compensation?

The term "on duty" refers to any person performing operations for a licensee, regardless of compensation. This designation captures anyone actively engaged in work on behalf of the licensee, regardless of their employment status or payment arrangements. It emphasizes the functional aspect of being engaged in operations rather than focusing on a formal employment relationship or specific contractual obligations.

In contrast, the other options pertain to more defined roles. "Employee" indicates a person who is specifically hired and compensated by the licensee, while "contractor" refers to an independent entity that might be retained to perform specific work but operates under a different arrangement than a traditional employee. "Agent" typically implies a person authorized to act on behalf of another, usually in a legal or business context, and often implies some form of financial arrangement or contract. Therefore, "on duty" is the most encompassing term for this situation, as it broadly applies to anyone actively working for the licensee.
