Not to advocate poor behavior however I wonder how many mainline pilots would be doing this or worse if they were bought out by another mainline and given a take it or leave it ultimatum contract. Then told to re interview for a mainline job that was never presented that way initially.

Not saying regionals should get date of hire like Comair tried but why the double standard system for a regional pilot and mainline? How many mainline pilots had to re interview when they were bought out by another mainline?
