Why is Alex considered not an effective team member?

Being considered an effective team member involves a number of qualities, but one of the most critical traits is dependability. If Alex is not dependable, this suggests that he cannot be relied on by his teammates to contribute consistently or to meet deadlines. Dependability fosters trust within a team, and without this trust, collaboration becomes difficult. Team members often rely on each other to fulfill their roles and support group goals, so if someone is frequently absent or fails to complete their tasks, it disrupts the team dynamics and overall performance.

In contrast, while avoiding conflict, being overly critical, or working alone may introduce challenges and hinder teamwork, they do not directly undermine the foundational reliability that dependability provides. A key component of effective teamwork is knowing that each member will contribute their fair share, and failing in that regard directly impacts the team's success.
