Weingarten rights are the rights of employees to request a representative during an investigatory interview with a supervisor. The right was established by the Supreme Court in 1975 in the case NLRB v. J. Weingarten, Inc.. The right applies to employees in a bargaining unit and can arise at any stage of an investigation. An employee's Weingarten representative can be a union steward, business agent or officer, or fellow employee. The representative can provide advice and active assistance, but they cannot answer questions on behalf of the employee. The representative may also ask to hold a private caucus with the employee during the interview. Employees are entitled to representation if they reasonably believe that the interview may result in disciplinary action, and they request representation. Examples of investigatory interviews include:
