But it should seem pretty obvious that something like maternity leave couldn't, and shouldn't, be an "earned benefit" - should everyone except to accrue a month of "maternity leave benefit" through the ages of 20 and 40 or something?
It's good that we do have benefits that only apply to subclasses of people (i.e. parents), but how those benefits are structured shouldn't be at the whims of a company if we feel, as a society, that they're important for people generally.
I think it would be reasonable for an employer to make some benefits, including certain paid leaves, subject to some minimum tenure. How an employer chooses among those options tells you something about them, but I don’t think a blanket “you cannot offer any benefits subject to tenure” makes a better world.
I do agree with you that if society thinks a benefit is important, society can pay for it directly. Or pass a law to mandate employers (or certain employers) to provide it.
