Why mention the Polar scope and rights of succession? It would only gum up their argument.
How so? There is no argument. Bob will be the first to tell you he is trying to prevent the merger, That is plain to all of us. However, the Polar scope clause does not give him the right to do so - though he and Robin are certainly trying.
So are you still at Polar layinlow?
Is it possible / realistic that DHL, when tired of wrestling with Polar labor, will walk away from it's hefty investment?
Most contracts have an escape clause, or a non-performance clause, or at least a date that it will all be accomplished by. So yes - I think it is entirely possible that DHL/Deutsche Post will dump a recalcitrant pilot group based on at least non-performance. Don't you.
