Check Airmen have integrity at "my house" too. If yours don't, you need to call your POI, instead of complaining about it on the FI boards.
There are only two possibilities here:
1) Yours is the ONLY airline where such high, unwavering standards occur.
2) You don't know what you're talking about and are totally clueless.
Since just about all of us know at least a couple pilots with questionable ability at your airline who are flying the line, I'm going to conclude that your airline is no different than the rest.
