A comment from me as a woman.
Assuming Minogue's converyed the story accurately...
If I ever got pregnant and the company grounded me on full pay, I would be so thankful to the company! The reasons that immediately spring to mind are 1) pregancy is not an illness but is self-inflicted, so it is generous of the company to offer the full pay 2) if I had not thought of the risks of flying while pregnant, I would be thankful to the company for protecting myself and the unborn.
I would have thought that the increased risks of incapacitation is present at any time during pregnancy, due to miscarriage or premature birth to start with? Also the risks to the unborn of the cosmic radiation has not been ruled out as far as I know. One thing I read is that the effects of any radiation is greater for the newborn than to child/adult, so maybe the same applies to the unborn.
Anyway, who's this company? I would love to work for them!
