Taurus doesn't like to take sides in an argument, due to their Venus ruler. You may sometimes become the person your co-workers come to when they want a dispute ironed out, or be the voice of reason when a meeting's going off the rails.
Adopting conflict resolution on the job helps keep you from having to bear the brunt of unfair treatment, or becoming the de facto mediator.
You don't need all that drama in your life, so instead of trying to be fair to all, know when to stay out of it entirely. Focusing on your own career goals, while being respectful of others you work with, gets you exactly where you need to be.
