Via the AFL-CIO blog I found Writing from a Kindred Voice: The Workers Writing Project, and I highly recommend the audio section.
In particular, check out the two by ex-steelworker Jeff Maines. “Appalachian Apologia” is about an older worker–a “hillbilly”–at Inland Steel, and “Thirty” is a staccato rap-like poem covering Maines’s 30 years in the mill. I also liked “Indiana Harbor Jones” by Bill Corrigan.
I hope to use these at this years Steelworker Summer Institutes.
