To be marginalized is to be cheaper. All else equal, the cheaper worker will be given preference during hiring. So long as the worker remains cheaper, all else equal, the cheaper worker will also be given preference during layoffs. If the worker works their way up into a position that they are no longer cheaper, they won't be given preference, but they also aren't marginalized anymore so you would't expect preference.
