> Many of the employees calling former colleagues also ask for advice on the best way to leave Facebook, according to multiple former employees. This is because the company categorizes departing employees under one of two tags: "regrettable" or "non-regrettable" attrition. Being labeled as "non-regrettable" is the equivalent of getting blacklisted by Facebook and prevented from ever working there again. For anyone in Silicon Valley who wishes to work at a top company, getting a banned by Facebook cuts down job opportunities drastically.

Not working at Facebook again is fine, but why should another company know whether the employee left in a “regrettable” manner, unless the person did something really bad or illegal? This seems like an egregious failure of privacy and an unfair branding of people.
