While the boss isn't supposed to play favorites, almost everyone who's worked in an office can tell you it's something that sometimes happens. An article in The Harvard Business Review asks what do you do when the boss has a clear favorite, and it's not you? The article says it's best to avoid negativity and resist the temptation to take out your frustrations on the favorite. It does nothing to benefit you, and can give off a poor impression. Instead, try building bridges and making connections to both the boss and the favorite. However, if despite everything else, you're still feeling frustrated at the situation, the HBR says it might be time to start a job search.
