Back to work without at least the improved hightlights seems odd!
Not really. It takes time to get the MEC together for a meeting in which they can vote on the agreement. It wouldn't be appropriate to release information about a TA until the MEC has had a chance to read it thoroughly and vote on whether it will go out to the pilots for a vote. That's going to take about a week from when the TA was actually reached. It's not in anyone's best interests, including the line pilots, to remain on strike for an additional week for no reason at all. If the pilots vote down the TA, then you can immediately go back on strike. There is no requirement for an additional cooling-off period of even more negotiations. A strike can begin right away again.
I think it's a bit crazy that guys here are attacking a TA that they haven't even seen yet. Your MEC conducted an incredible strike, with absolute unity. They stood up to management and held their ground until they got a fair deal. I think you can give them the benefit of the doubt until the details come out next week. Trust your reps. They are top-notch.
