What is the author's tone in Rivethead: Tales from the Assembly Line by Ben Hamper?

The tone used in Rivethead: Tales from the Assembly Line by Ben Hamper is definitely partisan and biased. The book is written in the first person point of view through the eyes of the author.

Hamper talks about the first time he ever stepped inside the General Motors Fisher Body plant, where his father worked on the second shift. It was Family Night. The loved ones of the workers could get a firsthand view of what the linemen tolerated on a daily basis. Hamper recalls the scene. "The noise was very close to intolerable. The heat was one complete bastard. Little wonder that the old man's socks always smelled like liverwurst bleached for a week in the desert sun."
