I am not on Bloomberg's side. Expecting employees to put work above all else is a recipe for misery for all but workaholics, and an ugly manifestation of corporate greed. But putting children above all else is not the answer for everyone either.
Judges lack the power to force employers to facilitate humane work schedules, and in a free market with more workers than jobs, employees lack the leverage to reach company- or industry-wide bargains for a better balance. At least for now, people who choose to have children will have to make trade-offs to pursue their dreams the same way that people without children do. Under the Pregnancy Discrimination Act and Judge Preska's ruling, pregnancy and related medical conditions are not a part of that trade-off – they should have no different effect than any other medical condition.
If other "work-family" trade-offs continue to fall more heavily on mothers than fathers, they will have a discriminatory effect. The most immediate and attainable palliative is for fathers to step up and mothers to step back. As more fathers take more parental leave the stereotype of women as children's natural caretakers will begin to erode, and if women take less leave, the stereotype that women are not as committed to their work as men are may begin to erode too. Parents who can afford for mom to take non-medical time off with the kids should not wait for the courts or the legislature to solve their childcare challenges. They should tap underutilized in-house talent instead: dads.
