Employees who are not represented by a union also have rights under the NLRA. Specifically, the National Labor Relations Board protects the rights of employees to engage in “concerted activity”, which is when two or more employees take action for their mutual aid or protection regarding terms and conditions of employment. A single employee may also engage in protected concerted activity if he or she is acting on the authority of other employees, bringing group complaints to the employer’s attention, trying to induce group action, or seeking to prepare for group action.
