If this incident is typical of your manager’s overall skills, perhaps he is the one who should not be receiving a raise. Your manager should be making decisions based on a direct understanding of your performance.
At the same time, your manager should also be willing to listen to input from other managers, especially if you do any work for them. In this case, if your job responsibilities include projects with this other manager, then it would not be surprising to find that he or she has some influence with your manager.
As a result, you should look carefully at your own performance, especially on work that involves this other manager. If your work has nothing to do with him or her, then your manager is the problem. And if your work does involve this other manager, the next step is to do your very best on such projects, make sure this manager knows it, and make sure your own manager knows it as well. Doing some internal public relations on your accomplishments can help build these relationships as well as your earnings.
