Q-1 Motor Express was an interstate trucking company. When a union attempted to organize Q-1’s drivers, it met heavy resistance. A supervisor told one driver that if he knew what was good for him, he would stay away from the union organizer. The company president told another employee that he had the right to fire everybody, close the company, and then rehire new drivers after 72 hours. He made numerous other threats to workers and their families. Based on the extreme nature of the company’s opposition, what exceptional remedy did the union seek before the NLRB?
