Labor law generally concerns compliance with the National Labor Relations Act (NLRA). The NLRA controls all aspects of the union/management relationship, including union organizing. While often thought of as a law governing only unionized employers, the NLRA also protects the concerted activities of two or more employees in non-union workplaces. Therefore, all employers must consider the law when developing policies, or responding to group conduct, such as employee use of social media to communicate concerns about wages, hours, or conditions of employment.
