What steps must a union take in attempting for a bargaining unit?

To establish a bargaining unit, a union must first gauge interest among workers and educate them about the benefits of union representation. Next, the union needs to gather signatures from a sufficient number of employees (typically at least 30% of the proposed unit) on union authorization cards to demonstrate support. After securing enough support, the union can file a petition with the National Labor Relations Board (NLRB) to request a union election. Finally, if a majority of employees vote in favor of the union during the election, the union can be certified to represent the bargaining unit.
