Not getting along with your fellow employees is an often ignored obstacle to getting a promotion. Most people assume that their colleagues are the competition and thus there is no need to get along with them. This couldn’t be further from the truth. More often than not, promotions are given to employees who get along with their colleagues as it means that they will be able to do well in the superior positions due to the support they have. If you are the mean employee that everyone avoids, you should do something about that and establish healthy professional relationship and rapport with your colleague.
