## Illegal union-busting

In May 2019, following a complaint filed by the United Steelworkers in November 2017, an administrative law judge with the National Labor Relations Board (NLRB) found that Kumho Tire had engaged in "pervasive" illegal conduct during a unionization campaign at the company's tire manufacturing plant in Macon, Georgia, with at least 12 managers including the company’s CEO issuing illegal threats to lay off employees or to close the plant if it unionized, as well as illegally interrogating employees and creating an impression of surveillance. The company was subsequently required by the NLRB to read a notice to all of its workers at the plant outlining the ways in which the company had violated their rights.
