Look around and see how much has changed about work and the worker. It is a clear signal that we need to redesign HR. So drop the assumptions of rational human beings. Maybe we will call it Behavioral HR. Google already has taken a lead in this space by starting a lab called Irrational Lab. Maybe it is time for all organizations to start one too where HR will remove outdated policies and replace them with ones that assume people do not make rational choices (mostly).
