This study is to evaluate the relations among the attitudinal ambivalence, behavioral intention and safety behaviors of workers, and the effects of leaderships on attitudinal ambivalence and behavioral intention. We collected 1,236 valid questionnaires from the 1,466 responses received(response rate 76.4%) by stratified sampling 64 companies. We have found that the attitudinal ambivalence does affect the safety behaviors through behavioral intention as a mediator and leader characters as a moderator. We conclude that the level of fondness a worker for a safety operation procedure is the essential factor to practice a safety act. Consequently, we suggest managers should conduct authenticleadership or self-leadership to trigger workers to behave safety acts.
