On the other hand, and depending on the airline ethos, duck shoving complaints to management types up the line, more often than not earns you the title of "maker of waves" and complaints are shoved under the office carpet with an under the breath exhortation that you are the captain of the aircraft - it's your problem - not management's. Fix the bastard yourself.

Occasionally, the threat of downgrading the errant First Officer to a lower fleet has the desired result.
I have seen it happen several times....with superb results.
