I haven’t seen a single instance of an FO contemplating a tactical fatigue call out. Not once.

Only one guy fatigued on me and scheduling had run him so far around the town square that it was legit. He looked wrecked. He was going to take me home to base through a hub. Wake up and do the morning flight back to ATL.
Of course I wanted to go home, but dude, he was wrecked and if I take this guy flying cause he feels bad for me then I am just a selfish unsafe a-hole.

You don’t know what’s going on. Don’t question’s fatigue calls brothers and sisters…..and non genders
