What problem did working class women face during the industrial revolution

They were paid far less than male workers doing the same job. (APEX)

Women worked long hours - sometimes 80 hours a week - often under horrible conditions. Remember, this was before the days of labor laws. The factories could basically set whatever policies they wanted, and workers were more or less powerless to do much about them. Conditions were often unsanitary and dangerous. Men typically held supervisory roles, and with that sometimes came sexual harassment and forms of discrimination and abuse. Women were usually paid less than men, and they were not treated equally.

Otto Von Bismarck played his cards very carefully, hoping for a Russian alliance and French neutrality. Once France realized that a United Germany was a power that could threaten the them, they went after the smaller southern German states that were not yet united with the north. Bismarck made it look like the French were the aggressors and convinced the states to unify with the north. After Prussia defeated them, they declared the birth of the German empire at the French palace of Versailles, making Wilhelm ll the new Kaiser.
