This, first & foremost, is the most important point. BA, or any other company for that matter, is not a charity.
The sale of BACon to FlyBe should be seen by the employees as a good thing (in the medium-long term) as you'll at least be working for a company that is committed to regional ops. BA will, one day, be an exclusive business/first class operator of point to point long-haul flights.
