What percentage of affected employees must support a petition for an election filed with the NLRB?

To initiate a representation election through the National Labor Relations Board (NLRB), a petition must be supported by at least 30% of the affected employees in the proposed bargaining unit. This requirement is set to ensure that there is sufficient interest among workers in forming or joining a union, allowing the NLRB to determine if there is a legitimate need for an election. The 30% threshold is designed to represent a significant portion of the workforce without being so high that it would hinder the ability of workers to organize. Once this threshold is met, the NLRB can move forward with the process to hold an election, allowing employees to vote on whether they wish to be represented by a union.
