I cannot speak for everyone but my observation is that many pilots choose to stay and are trying to get a fair and equitable contract.
If every pilot group in the past resigned just because contract negotiations were going poorly then you would never see the likes of current Delta pay rates. These contracts were fought hard for by those that came before us.
The new hires coming on property today are interfering with that and dragging the process out. Failure to secure an industry leading contract with Indigo will set a precedence for the rest of the industry. All eyes should be on us right now.
