Final answer:
The most suitable leadership style to adopt in this situation is a delegating leadership style.
Step-by-step explanation:
Based on the information provided, the most suitable leadership style to adopt when working with the fundraising team is the situational leadership approach. The situational leadership approach suggests that leaders should adapt their leadership style based on the readiness and competence of their team members. Since the team members are competent and experienced fundraisers, a delegating leadership style would be appropriate.
This style involves giving the team members autonomy and trust to carry out their tasks independently. Instead of providing detailed instructions, the leader allows the team members to make their own decisions and take ownership of their work. This approach not only leverages the expertise and motivation of the team, but also fosters a sense of empowerment and responsibility.
