Management bias
Management bias – a lack of neutrality by management in the preparation of information [International Federation of Accountants].
Manager bias refers to managers' unconscious biases about the people they manage or work with. These biases can have a significant impact on employee productivity and satisfaction. For example, some managers may stereotype employees as lazy or unproductive, leading to ineffective decision-making and a decline in team performance. The bias may become self-serving, the employees become disinterested, and their productivity falls as they are aware of their perceptions [Risely].
