Under which of the following circumstances may a licensee be employed by more than one broker?

While working in a branch office managed by an associate broker may involve some level of collaboration, it does not inherently grant the licensee permission to be employed by more than one broker. The regulations specifically require written approval from all employing brokers, regardless of branch office management.

The geographic area in which a licensee sells properties does not determine their ability to work for multiple brokers. Employment by multiple brokers is contingent upon obtaining written approval, not on the distance of property sales. Therefore, this choice is irrelevant to the licensing regulations.

This statement is incorrect as it misrepresents the licensing regulations. While there are restrictions, a licensee can indeed work for multiple brokers if they secure the necessary written approvals. Thus, this choice contradicts the possibility outlined in the correct answer.
