While I agree with what you say Eddy with regard to the bonus, at some point there will have to be some kind of reconciliation between the warring parties. This may take a long time and it may be a difficult process but someone has to start to be reasonable.
In the grand scheme of things this is small issue. I suspect it will make no difference whatsoever but I applaud KW for trying to take some of the bitterness out of something that ought to be a trade dispute without the rancour that exists.
If BASSA continues to behave true to form, their reward may well be significantly altered contracts through a 90 day notice of change. If that is the end position of BA should BASSA continue with their corporate stupidity, KW may be offering the olive branch so that he can say "well I tried but they just will not see reason - issue to 90 day notices".
