1) How did the workers mobilize themselves against the Robber Barons in the 1800s? a) Rioted b) Slowed down work c) Boycotted buying products d) All of the above

d) All of the above

Explanation:

The Robber Barons of the 1800s ran large enterprises that made huge profits at the expense of the working class. They would pay low wages or increase prices to make even more from workers.

Workers resisted these in various ways such as by rioting, even though this was often put down by the government or the company itself and by slowing down work so that management would take note of their concerns.

They also boycotted buying goods so that the profits of these enterprises would suffer and they would be forced to do better by their employees.
