The National Labor Relations Board announced recently that unions should be required to show that established, systems are in place in order to track grievances and communicate their status to workers. Unions that do not do so may be liable and at fault for poor representation if failing to process worker grievances in a timely fashion. Prior to the new policy, unions were only at fault if they had acted in bad faith. The labor board said that there had been an increasing number of cases where the union had defended itself due to negligence rather than it had acted in bad faith.
