Is your workplace or union dominated by the same old patriarchal bullshit? Do your "comrades" have no idea what feminism has to do with organizing? Are you trying to learn more about how sexism and capitalism are entangled? Here are two chapters on gender and work from The Housing Monster, for your printing and distroing convenience.
You can find the full book free online, and many more lovely zines, at prole.info. The bound book can be ordered through PM Press (pmpress.org, or, again, prole.info).
