I think that if Congress was still controlled by Republican conservatives, Dougie may have gotten some attention.
Being that the House has changed control, I suspect Dougie will have a hard time convincing Congress that his intentions are good for the consumer and not self serving for he, and his cronies. Congress has passed the min. wage bill as the "first order of business". That places many of the employees of U just a little above min wage, if not at min wage for the newer employees. With regard to Medical costs for these employees, they can't afford it.
In addition, Congress doesn't have a short memory and I am sure the majority remember the history of U the past 3 years, their treatment of the employees and the flying public as well as how much the execs benefited during U's time of financial crisis.
The mood of the U employees has not shifted since then. I don't believe they will support any kind of merger unless they will directly benefit financially, other than keeping a job.
