I have been told that BK has a lot of "alternative options" to deal with this, including "employment in Europe" through Rishworth , alternative A.O.C's etc etc.
The protestations may delay things a bit, but, in previous actions the operation has continued to grind on whilst the details were hammered out.
Importantly, I doubt if any of this will have the useful side effect of raising the T's & C's of those currently employed, nor of those in the future.
Seems there are more than enough folk tempted by the current uninspiring package to harbour any dreams of it getting significantly better.
