No one in any business cares about their customers or coworkers any more than they have to. Why would you think that the person at the supermarket cares about the weird story you have to tell them?
HR doesn't care about you because they don't know you. Your coworkers barely care about you. Do not think people you work with are your friends. HR has no moral reason to do anything other than their jobs. Don't rely on them for legal advice. They are just a mouthpiece for what has already been decided.
