Unfortunately the regional airlines don't care if you leave, they know they can replace you very easily. There are thousands of young flight-instructors, or kids flying cargo in C402s who would agree to any salary in-order to fly a jet. These kids won't fly a jet for free because of the stigma that comes with that, but short of that, they'd take anything. The regionals know that and the majors know that as well.

If you are a senior pilot at a regional, you would actually be doing them a favor by leaving, they'd replace you with someone cheaper (junior)
