The purpose of this investigation is to gather insights from construction workers regarding their perceptions of the impact personal stress may have on their own behavior, and, in turn, how their behavior can affect the safety and work quality of the entire construction crew. It has been found in this investigation that although personal stress is not always verbally shared with coworkers, it is recognized by colleagues via nonverbal cues. In addition, most construction workers report that they do not receive appropriate social support from their co-workers, despite their need for it.
