I've sort of been that employee once. In my defense, I am fully convinced that the designer was not a capable individual, unpleasant in many ways, and a general net negative to the company. But in hindsight, my way of dealing with him was probably more detrimental to the (very small) team as a whole, and if not for the fact that my role was more important than his, I'd probably have fired myself or at least given an ultimatum. Because in the end most of my issues with the designer did not keep me from doing my job. I just hated the guy... While the specifics might be different in OP's case, I do now also believe that team cohesion and basic 'professionalism' is often more important than the individual quality of a misbehaving team member.
