The only way to change employee racial composition is to hire and terminate on a racial basis. The only way to
force that composition to mirror social composition is to do so explicitly and strictly on racial basis.
A lot of factors go into proper hiring and terminations, most significantly the merits of the individual concerned. Such factors will lead to an employee racial composition that might not mirror that of social composition.
Certain hiring practices like favoring women for flight attendants and black men for basketball teams should be terminated with extreme prejudice, but to force employee racial composition and specifically that one way or any other is racism.
