Union busters, also known as labor relations consultants, are individuals or organizations hired by employers to prevent the formation of unions or to disrupt existing unions. They typically use tactics such as intimidation, bribery, and misinformation to discourage workers from joining a union. Union busters may also be hired to negotiate contracts with unions on behalf of employers. The term 'EXES' is an acronym for 'Exclusive Executive Services, ' which is a type of union-busting firm.
