Many stewards, even those who recognize the importance of using tact in dealing with fellow members, yell and bluster at their supervisor. In doing so, they may make the job harder.  It is much wiser to develop a relationship in which the supervisor is willing to cooperate with you and to handle grievances quickly and fairly. In some cases, this is hard to accomplish. Still, you may not get anywhere if you go out of your way to antagonize the supervisor. Have a strong, well-prepared case that is put together properly with accurate facts. However, grievances that are settled in a friendly manner usually stay settled longer. If possible, try to remain on friendly terms with supervisors. This will help you, especially when you have a weak, borderline case or MCO’s policy is not well developed. A relationship where each side is trying to rub the other's nose in the dirt hurts both.
