Appears the opposite is happening in Leeds. Aviance closing & Servisair allegedly taking on the business. If the law is an ass then it will balance itself out!
As for keeping all staff don't forget economies of scale. Effectively one company doing everything can be more efficient than two doing similar work separately. It all depends on how your flying programme fits together.
