We know that the poles had changed positions in the past, because of the arrangement of the crystals in the rocks made out of metal. The crystals of the metals act like the needle of the compass when the rock is cooling off and forming, they turn into the direction of the strongest magnetic field on the Earth, which is the North Pole. So by studying the rocks that are made out of metals and see the crystals arrangement and also estimate the age of the rocks, the scientist can precisely tell how has the North Pole been moving throughout time.
The Industrial Revolution made work be more regimented and less skilled. Instead of working for yourself, at your own pace, you had to work for a boss and work when and how hard that boss told you to. This made workers feel much less independent than they once had.
As for conducting business, things also became much more impersonal and regimented. Instead of conducting one's business as boss to a few apprentices and journeymen, a factory owner would now need to manage hundereds of employees.
So, in general, the Industrial Revolution made the workplace much more impersonal and took away the independence of the workers it employed.
