You see Pickuptruck, the difference is that Delta has paid out over $4 billion USD in profit share in the last few years. Because of this I’m sure all of its employees will wilfully sign up to any unpaid leave or other measures, and that will help Delta ride this out.
The sad truth is, that at CX, those that signed up to SLS, did so out of intimidation, and fear of retribution, not because they felt obliged to help out a company that has looked after them.
