no law compels a woman to have a baby, or take 2yrs' leave to look after it. maybe the husband shares part of the duty. maybe its the husband that looks after the baby. but conscription compels singaporean men to provide labor at well below market rates, in this case for 2yrs, plus ongoing resrervist cycles for the next decade or so. its like. by law singaporean women have 24hrs a day, men have 22. or something like that.
It actually makes situation for woman with children much worse, since she is alone while her partner is in military.
Gay couple with children, where both parents would have to go illustrates it well.
