There are employees out there who have suffered the misfortune of a colleague trying to cost them their job, even though they didn't do anything wrong. While they usually have one reason or another to have a chip on their shoulder, that doesn't justify trying to get someone fired. When those who had experienced this in the workplace were asked to share their stories, it was clear that an individual who has a problem in other areas of their life is likely to bring it into work as well.
While a bad boss is one of the most common factors in somebody leaving a job sooner rather than later, it can sometimes be the case that coworkers drive them out, too. That said, it is a lot more satisfying when your work enemy quits or gets fired themselves. The battle may be lost, but the war is won.
