Sawmill workers in the early 1900's
After using several search terms, I still can't seem to find what I'm looking for. I've googled Sawmills in 1900's, worker and working conditions of sawmills in the 1900's, historic sawmills of upper michigan, historic sawmills (general), early sawmill tools, early sawmills, operating sawmills in 1900's, early sawmill occupations, a day in the life of a sawmill worker, sawmill workers, and about every variation of these.
I've seen pictures of usually a small to moderate sized crew for these sawmills, and I need to know what job titles these workers held (those using the saws, or those maintaining the engines for the saws, those piling the wood for transport, etc.), what their job consisted of (daily duties), and what sort of wage would they be paid?
What equipment besides the circular saws would workers be using?
Then I would like to know what to call this character's boss. Manager? Foreman? Supervisor?
Would they wear ear protection because of the high whining of the saws? Would it be something they are supplied with or would they have to make their own? Would they have goggles or some sort of eye protection provided by their supervisor or mill owner?
And any miscellaneous info like terminology for that time would be useful. Nicknames for machines, or tools, or worker titles. What they might do during breaks or downtime.
