Captain and co-pilot roles are very similar. They both require the same piloting skills and qualifications, although the captain is usually more experienced than the co-pilot. The primary difference is rank - the captain is the senior of the two, and he is accountable for the flight. The co-pilot reports to the captain and takes his orders from him. The captain's additional experience and responsibility means he will earn a higher salary than the co-pilot. The captain also gets to wear four stripes on his uniform, while the co-pilot has three.
Unreal! I wonder if their client knows this is the level of HR muppetry being made public?
