What type of behavior is exemplified when someone stays late to help when the team is short-staffed?

The behavior of staying late to assist when the team is short-staffed is a clear demonstration of self-discipline. Self-discipline involves the ability to manage one's time and actions effectively, particularly for the benefit of the group or organization. In this scenario, an individual shows a commitment to teamwork, prioritizing collective goals over personal convenience.

This act requires the individual to resist the temptation to leave at their regular time and instead make a conscious choice to contribute to the team's needs. Such behavior reflects an internal motivation to maintain productivity and support coworkers, characteristic of a disciplined mindset.

The other options do not align well with this behavior. Financial literacy pertains to understanding financial concepts, which is unrelated to the act of supporting coworkers. Comfort engaging with strangers relates to social interactions, not teamwork in a work setting. Pessimism describes a negative outlook, which contrasts sharply with the proactive and supportive nature of staying late to help the team.
