The psychological contract refers to the set of expectations between an individual and the organization regarding what each will contribute. The person-job fit concerns how well an individual's contributions match the organization's inducements. Personality traits like the Big Five (agreeableness, conscientiousness, emotional stability, extraversion, and openness) as well as locus of control, self-efficacy, and risk propensity influence individual behavior at work. Leadership involves using non-coercive influence to motivate others toward goals and help define organizational culture. Situational leadership theories like path-goal theory and leader-member exchange focus on how leader behaviors should adapt to situations.
