Answer:
The correct answer is 1. They hired workers to cross the picket line if a group of workers went on strike.
Step-by-step explanation:
During the American guided age, labor unions and strikes were increasingly becoming a problem for business owners. Labor unions not only demanded better wages or better working conditions, many were using it as power grab to take over manufacturing units and try to control everything.
In order to combat this, many business owners had hired workers who would try to create misinformation, confusion and distrust among the union members. The idea was to dissolve a strike before it can take place.
