An FO is a Captain in spe, meaning that every flight should be a learning experience, guided by his or her Captain.
Those unwilling to share their knowledge and experience are either too incompetent to be Commander of a Jet or too lazy to be Commander of a Jet.
Go and tell this
to the Southwest Airlines FOs with 6-8000 hours and a previous experience as CRJ or Dash8 captains. An FO is not here to
learn, he is here to work efficiently within a team as safe as possible. He needs knowledge and skills.
