In the case of NLRB v. Weingarten, Inc., the National Labor Relations Board (NLRB) addressed the rights of employees during investigatory interviews. The Supreme Court ruled that employees have the right to request union representation when they believe that an interview could lead to disciplinary action. This decision reinforced the importance of collective bargaining rights under the National Labor Relations Act. The ruling established what is now known as "Weingarten rights," which allow employees to have a representative present during questioning by their employer. This case highlighted the balance between employer authority and employee rights in the workplace.
