Some people's claim to fame end when they get promoted, and from then on they simply sit at their desk, playing Candy crush on their phone, overlooking a bunch of other employees, not doing any more actual work. Either they aren't very self-aware when they expect to get glowing references from former coworkers, or they're downright delusional. Either way, if you're not gonna work, don't expect the people you effed over to vouch for you when you begin looking for another job.
