Have you ever worked in a factory?
No I have not, but my uncle did. Factories arose with the introduction of machinery during the Industrial Revolution.
I know that factory work is hard work.  especially back in the Industrial Revolution time
This was an important transition of going from hand production to machine production.
Yes it was and now basically machines can do all the work for us
The Industrial Revolution began in Great Britain.
Interesting I didn't know that
Yep and many of the technological innovations were British.
Well the British I guess had a step up on us
It seems like they did. Modern factories now have large warehouses and assembly line productions.
