The Industrial Revolution changed pretty much everything, and one of the things that changed significantly was the labor. Prior to the Industrial Revolution, the majority of the people were working on the agricultural fields, thus they directly depended on it.

The people started to work indoors, which is an improvement as the outside effects were not bothering them anymore. Also, they were getting better wages, had fixed working time, and they were paid on much shorter periods, usually monthly, which brought greater economic stability of the people.
