What are the rules for starting a union in a public company?

To start a union in a public company, employees must first express interest in forming a union, typically by gathering support through a petition or obtaining signatures from a majority of workers. Next, they need to file a petition with the National Labor Relations Board (NLRB) for a union election. If the NLRB approves, an election is held, and if a majority of participating workers vote in favor, the union is officially recognized. Employers are prohibited from interfering with this process, and workers have the right to organize without fear of retaliation.
