Managerial ethics are moral principles that guide a manager's actions and behaviors in the workplace to create an environment that is welcoming and inclusive. There are three main types of management ethics: immoral, moral, and amoral. Approaches to management ethics include the utilitarian approach which analyzes the effects of decisions, the moral rights approach which protects fundamental human rights, and the social justice approach which ensures fairness. Key aspects of being an ethical manager include defining values, hiring employees with similar values, promoting inclusion and open communication, and leading by example. Managerial ethics are important as they create a positive work environment and help maintain strong professional relationships and collaboration.
