It's no joke. Despite all her claims to care about people and all her "it takes a village" rhetoric, she is condesending and dismissive to people at work. In the WH, she was known for being awful to the house staff, sometimes telling them to "shut up" and "get out" and once a F--K you to a doorman wishing her a good day. Tempermentally, she is no better than Trump, and he is probably actually a nicer person. Despite what she says, the only person that Hilary cares about is herself. And don't forget that she was the major strategist to get Bill through the intern schedule.
BTW, who did former WH staff think was the best to work for? The Bush Srs. They were used to dealing with staff, and treated them with respect and kindness. The Clinton's were the worst.
