It is what it is, you all read /speak/ understand English yet you need someone to explain what TA REALLY means. Who is ignorant one?

Go to reeducation camp, so they can tell you what to think about TA. Then reflect on what you were told when you open cockpit door to find 20 years old gate agent with big smiles telling - may be ordering - you to call scheduling. Then all you can say is yes maam, then call scheduling to get your beating. At least you get extra pay even if lower rate than peers.
