If Your Rights Have Been Violated
If you believe that your union has not lived up to its duty of fair representation, or even if you have concerns about the quality of the representation provided, your first step is to sort out what happened and why. It's simply not fair to your co-workers who have stepped forward to do the union's work to react by making accusations without first checking out the facts. So approach your steward, or anyone else who had responsibility for the action you are unhappy about, state your concerns, and try to listen with an open mind to whatever explanations are offered.
