What type of director is expected to work full time in management?

An executive director is expected to work full-time in management because this role involves actively participating in the day-to-day operations of the company. They are responsible for making strategic decisions and overseeing various departments, which requires a significant time commitment and direct involvement with the organization's activities.

In contrast, a non-executive director typically does not engage in the daily management of the company and functions more in an advisory or oversight capacity. A shadow director, while influencing the board's decisions, does not hold an official title and may not be involved in the operational aspects. An alternate director serves as a substitute for a regular director but does not inherently imply full-time involvement in management. The responsibilities and expectations of an executive director align closely with active management roles, making them the correct answer for this question.
