Employees or a union may file a petition for a representation election (RC) after collecting signatures from at least 30% of workers in the potential bargaining unit. Petitions that are not withdrawn or dismissed result in an NLRB-conducted election. A majority of votes decides the outcome. Please note: Some petitions filed in a given year may not have an election until a subsequent year. Thus, the number of petitions may not equal the total number of dispositions in a given year.
