The individual and situational factors predicting unethical behaviour in the workplace: a direct and conceptual replication of Jones & Kavanagh (1996) Open
Intentions to act unethically in the workplace are purported to be driven by a number of situational and individual factors. Across two seminal vignette experiments, Jones and Kavanagh reported inconsistent effect sizes for manager and pee…
