Question

Quizplus · Accepted Answer

A labour board can certify a union without an employee vote if the firm has been found guilty of an unfair labour practice which hindered the vote. In such cases, the board may waive the requirement for a vote and may certify the union based on other evidence of employee support, such as signed union cards or other forms of employee support.
