I did not look at the recent one, because I am basically lazy, but I would have been surprised if I had never noticed a provision like that. My guess is that it dates back a long way, and has hung on in the 802 agreement because no one cared enough to take it out. One other observation: these are not the kind of provisions that work even when they are present. Exceptions are better dealt with as they arise (and they are, generally). We are in uncharted territory right now (an understatement) and there was an opportunity for a leader to step forward. That did not happen, for a variety of reasons. So we have informal ad hoc leadership, not necessarily palatable, and not effective as we have known since the passage of the Wagner Act. One more thing: anyone who thought Kevin McCollum of all people would send his books to a union has lost their mind.
