It'll start off nice but you'll quickly realize that you're in high school again - Mitarbeiter (anonym) bei Sixt: Mitarbeiterbewertung

Management is easily threatened by and believes office gossip that tends to be factually true about 9 percent of the time. It gets even worse when you notice that management actively participates in these rumors. Or that except for maybe one or two people, every employee that is no longer there has been fired/left on bad terms. You might think that you won't be one of those people, but the HR department specializes in blindside firings. Be very careful about what you say because it most likely will be twisted and used against you. At least in court you have a lawyer to defend you, at Sixt you have no one.
