Final answer:
In the United States, at least 30% of employees in a bargaining unit must sign authorization cards for the NLRB to hold a union representation election. This is part of the journey towards forming a union, which contrasts Canada's process where approximately 60% of employee signatures on an official card are needed without an election.
Step-by-step explanation:
The minimum percent of employees in a bargaining unit who must sign authorization cards for the National Labor Relations Board (NLRB) to hold a union representation election is 30%. This threshold is required as part of the process for forming a union in the United States. Once this requirement is met, an election date is set where employees will vote in a secret ballot on whether to form a union. The process in Canada is different; rather than a secret ballot, a union is formed there when approximately 60% of workers sign an official card in favor of unionizing, without an election date.For example, if there are 100 employees in a bargaining unit, at least 30 employees must sign authorization cards for the NLRB to hold a union representation election.
