With the information age, organizational climate and managers’ approaches to employees have become extremely important for employees to reveal their potential. Employees who are valued, take initiative in their work, participate in decisions and have knowledge about organizational activities contribute more to the achievement of organizational goals. In recent years, a mushroom management approach has emerged that requires employees only to follow instructions with insufficient knowledge. This approach expresses an autocratic management style that advocates leaving employees in the dark like mushrooms, focusing only on their work, not questioning managers’ decisions, and deliberately avoiding sharing knowledge and experience with employees. On the one hand, hiding information from employees can have positive results; on the other hand, it may cause negative results. For this reason, managers need to learn with whom to share strategic information in order to protect enterprise secrets and privacy. However, it can be said that the reasons why managers hide information from their employees with malicious intent, and high ego and exaggerated pride are reflections of dark leadership characteristics. In addition, employees’ insufficient knowledge about the enterprise reduces employees’ positive attitudes and behaviours towards the organization. As a result, it can be stated that it is a wrong approach for managers neither to maliciously hide enterprise-related information from employees nor to share all enterprise-related information with employees.
