Yes, they could do many things to piss us off next week but not much to help sort out the real problem, and experience tells us that pissing the aircrew off is higher up their priority list than solving problems, so that's what we can expect.
News from negotiations is that its the same old people pulling the same old sh!t so we can probably expect no agreement in the room and AT bringing in a slightly improved (but still substandard) offer on June 1st if she wants to deal. There is some hope as SK isn't too heavily involved but I'm tempering my optimism!
