If you're talking about factories back in the day…
Think of the Industrial Revolution. ESPECIALLY in England. People were flocking to big cities where factories were so they could get jobs. This caused over population and a lot of struggle.
Factories were overcrowded, dirty, and very "harsh". Children were a big issue during this time because owners used them for work and they were so young. There were a lot of injuries, fires, and such because of just the lack of control in factories.
Now a days, we have learned from our mistakes and made factories cleaner and MORE ORGANIZED.
