In as much as I believe that the WW remark is just a troll, what I will be interested in is the career of the current NATS CEO. If or when the current chief carries out a cull and if it is perceived as being unfair or otherwise amongst the remaining workforce, it will make ongoing workforce cooperation very difficult if not impossible. Workers will realise they are simply an asset to be used and disposed as and when deemed necessary by the company, this realisation doesn't exactly produce workplace harmony or a happy atmosphere.
Someone that carries out a massive chopping session may well find that they themselves will have to voluntarily move on and for fresh faces to come in and try and pick up the remaining pieces of morale in order to put what's left of the company back together again - not an easy task.
It's always easy to manage a company when it's all going well and trends are upwards, you really see true personalities when things turn sour. Words are cheap, actions always much louder.
