A junior team member's suggestions are repeatedly rejected by senior members, who view them as innovative but unrealistic. After several assignments, the seniors ask to remove the junior member. What should the project manager do next?

Encouraging deeper discussions among team members is the best next step because it addresses the root cause of the conflict: a lack of understanding and potentially a communication breakdown. The junior member's ideas are seen as "innovative but unrealistic," suggesting a need for more detailed explanation from the junior member and more open-minded consideration from the senior members. This approach fosters collaboration and allows for potential refinement of ideas. Removing potential conflicts from future assignments or removing the junior member avoids addressing the underlying issue and can lead to loss of valuable perspectives. Grouping new team members for training might be beneficial generally but doesn't directly resolve this specific interpersonal conflict.
