I doubt that there have been any women workers who didn't demand more wages and better child care facilities/benefits _at the same time_. I don't know if Jim has any particular situation in mind; if so, I'd like documentation.
In any case, if some women have demanded company child care facilities as 'women and mothers,' well, that's simply because it has been, alas, women and mothers who have shouldered the majority of private care-giving work (which is _not_ limited to child care -- it includes taking care of the sick, the aged, the disabled, etc., may I remind you). If men had taken an equal responsibility for care-giving, a demand for child care benefits/facilities would not have come as one based upon the needs of female gender. Before criticizing 'identity politics,' you might attack the gendering of care-giving work, both in the 'domestic' and 'public' spheres.
