Half a cake is better than no cake.
This is true. However, on principle I will not work for a company for half a cake when it used to pay me a whole one and can still afford to. If I'm forced to work for half a cake, I guarantee you it will not be for BA. I won't especially enjoy watching them sink but there will be an element of satisfaction knowing that I won't be spending my remaining career working for a bunch of thieves.
