Monthly material usage

im courious as to why a company,whos employmet and production level is set lower than 100,still consumes the same amount of materials. I cound understand why factory matinance might stay the same but others should decline.OR am i mistaken

I think you are mistaken. I checked 2 corporations that had less than 100% employment. The "cost of raw materials" chart match the number of employees almost perfectly.

Note that supply page says that the supply usage is based on 100% hiring. RC is correct.
