So read the sub-text here..what happens in the minds of some old-school men on the potential and skills of women, as soon as woman gets pregnant.
That would be THEIR problem, not that of the pregnant woman. In the States, it is illegal to discriminate against a woman for being pregnant or being a woman who could get pregnant. How ever "old-school men" feel about it is irrelevant. Until a workplace sets a policy against baby showers and other such things at work, then people are free to think what they like. If those "old-school men" choose to ACT on those thoughts, that's another matter entirely.
