You want to get as many sec TAed as possible. It puts pressure on management assuming you’re making gains. At some point before a cooling off period can begin Alpa will petition for a proffer of arbitration. It could be denied, Crickets, (like last time), or accepted. If accepted, What that means is both sides can agree to let an arbitrator resolve all remaining open sections. Either side can say no to arbitration and now we’re in a 30 day cooling off period. In most circumstances it’s a bad idea to accept arbitration because you lose all control of those remaining sec. It’s not always a bad idea imo. It depends on what you have already TAed and the economics of current contract (compared to industry) and what has been TAed already. Point is it gives you the option to roll the dice on remaining open items. The fewer the better.
