Recently i found out one of my colleagues is incentivised on a group project at work. When I found out it felt like a slap in the face, especially since I lead meetings and offer training to other members of the team. I just feel like what is the point in doing that work if someone else is going to be rewarded fo it. I must add that I really like my colleague and I am happy that she is earning more, but on this basis I just don't think it's fair. What do I do? Should I bring it up with management
