A good point indeed.
I would add to it the whole issue of 'standards' used to define jobs , job responsibility, and work schedule that 'engender' work by making it more 'suitable' for men or women - but without overly sexist overtones. To illustrate, establishing a standard that requires 100lbs lifting autmoatically excludes most women but does not look like overtly sexist, until we realize that the 100lbs standrad is arbitrary.
The same can be said about work schedule which is designed with the male "breadwinner" and female "homemaker" in mind. Interestingly, the unions are in a very peculiar position here - fighting the loss of well paying jobs on the 'breadwinner' grounds would be politically suicidal. They use the euphemism the "living wage" but that assumes only one spouse working without explicitly mentioning it.
I think one of the intellectual weakness (pardon that dreadful term) of the union movement here is it inability to address the issue of the organization of work (cf. excerpts from _Underground Woman_ posted by Lou Proyect) that is not rooted in the (male) 'breadwinner' ideology. In that respect, capitalists with their notion of flexibility are far ahead of the unions and, I am afread, most of the Left.
