Phil, I think you have shown by this paragraph alone that you have no great knowledge of the why's the wherefore's or the outcome. Bye, bye.
Au contraire, No15, he has identified the nub of the problem the strikers face. Frankly'da management' don't actually have to do anything right now. They are making massive savings through MF and the fact that a large part of their workforce has turned down a pay rise thanks to their 'representation' via BASSA. The threat of a strike is empty since it has already been shown to be a dud, and will in any case jeopardise the livelihoods of any who participate.
For WW the dispue IS over . He has far bigger fish to fry - IAG, tying up with AA, acquiring other airlines etc. BASSA are just a sideshow now, with no power to even influence the transfer of routes to MF much less actually wring any concessions from their employer. No amount of huffing and puffing is going to change that fact.
