I've had a similar experience with a fellow co-worker. In fact, my manager also saw this as an issue but the toxic co-worker was too important to the team. I suffered through it for a year and ultimately left in the end (although for different reasons). I guess what I'm trying to say is, having a toxic co-worker isn't the end of the world. Keep on learning and do your job. If at the point you find yourself not learning as much and not enjoying your job (and your co-worker is still toxic), it means it's time to move on. By that time you'll have learned how to deal with and thrive around a co-worker who is "toxic". Live, learn, adapt.
