Sex-definedprotectivelawshaveoftenbeenbasedonstereotypicalassumptionsconcerningwomen'sneedsandabilities,andemployershavefrequentlyusedthemaslegalexcusesfordiscriminatingagainstwomen.AftertheSecondWorldWar,forexample,businessesandgovernmentsoughttopersuadewomentovacatejobsinfactories,thusmakingroominthelaborforceforreturningveterans.Therevivalorpassageofstatelawslimitingthedailyorweeklyworkhoursofwomenconvenientlyaccomplishedthis.Employershadonlytodeclarethatovertimehourswereanecessaryconditionofemploymentorpromotionintheirfactory,andwomencouldbequitelegallyfired,refusedjobs,orkeptatlowwagelevels,allinthenameof“protecting”theirhealth.Byvalidatingsuchlawswhentheyarechallengedbylawsuits,thecourtshavecolludedovertheyearsinestablishingdifferent,1essadvantageousemploymenttermsforwomenthanformen,thusreducingwomen'scompetitivenessonthejobmarket.Atthesametime,eventhemostwell-intentionedlawmakers,courts,andemployershaveoftenbeenblindtotherealneedsofwomen.Thelawmakersandthecourtscontinuetopermitemployerstoofferemployeehealthinsuranceplansthatcoverallknownhumanmedicaldisabilitiesexceptthoserelatingtopregnancyandchildbirth.
