There are a few examples in the military. Going back a few decades the RAF used to do the same as FlyBe - sack the pilot. They then woke-up and realised that the problem was real and, as an employer, it was their problem. There's a really good piece where an experienced (Tornado?) pilot describes how fear slowly crept-up on him and how he overcame it with professional help. Can't find the reference for the life of me though.
