A more thorough explanation:

A managerial employee is someone who performs managerial functions and is not considered an employee under the National Labor Relations Act (NLRA). This means that they are not protected under the Act.

For example, a CEO, a department head, or a supervisor who has the authority to hire, fire, or discipline employees may be considered a managerial employee. They are responsible for making important decisions that affect the company and its employees.

However, a receptionist, a clerk, or a janitor who does not have any managerial responsibilities would be considered an employee under the NLRA and would be protected under the Act.

The exclusion of managerial employees from the NLRA is important because it allows employers to have more control over their management team and their decision-making processes without interference from labor unions or other employee organizations.
