If they answered your concerns, ask yourself this - are their answers that you seemed to be pleased with written in the EBA, or is it just managements/FAAAs word?
For all those thinking the company/union word might protect you, maybe you should record one of the roadshows so you can play it back to yourself in the near future when you've been shafted for one reason or another- because even though it wasn't the companies "intention" now, who knows what it may be in a year or 2 or 3. How many times throughout negotiation history has it been necessary to "get it in writing"? This is no exception.
