How do you know they are getting seriously fed up with your perception of the Bassa attitude? Have you had a personal conversation directly with members of the management negotiating team or are you just repeating what you think they feel?
A friend of mine very recently spoke to both Willie Walsh and Keith Williams on the matter, and they were determined that changes would happen, regardless of whether BASSA tried to stonewall the company. Do you require more evidence that the management are fed up with BASSAs attitude?
