Well given our current SCOTUS, anything is possible. In Texas they have the "right to work" which is double speak for, the employer has the right to fire you. I dont think ALPA or any union will side with folks trying to get out of a safe vax that prevents the single largest threat to our industry. TONS of us were laid off or furloughed because of the virus and now there is a vaccine. If this vax was bad they would be giving it to poor people, not rich CEOs and Politicians. It may not be perfect but its better than the alternative.
