How did working conditions become worse in the late-1800s?

Explanation:

The dangerous machines, unpredictable mine explosions, and pollution from factories led to deteriorating work conditions and health hazards. Children who worked in textile mills and mines, especially in the South were put in dangerous positions.

Many workers in the late 1800s and early 1900s spent an entire day tending a machine in a large, crowded, noisy room. Others worked in coal mines, steel mills, railroads, slaughterhouses, and in other dangerous occupations. Most were not paid well, and the typical workday was 12 hours or more, six days per week.
