“The working woman may be quick to see any problems with children as her fault because she isn’t as available to them. However, the fact that she is employed is rarely central to the conflict. And overall, studies show, being employed doesn’t have negative effects on children; carefully done research consistently makes this clear.”
—Grace Baruch (20th century)
“Mothers are likely to have more bad days on the job than most other professionals, considering the hours: round-the-clock, seven days a week, fifty-two weeks a year. . . . You go to work when you’re sick, maybe even clinically depressed, because motherhood is perhaps the only unpaid position where failure to show up can result in arrest.”
—Mary Kay Blakely (20th century)
