I wouldn't worry about attrition here, the company is convinced they have tons of qualified people that want to work because this the best airline in the world.
I actually typed that last part out with only giggling a little instead of laughing loud enough for everyone in the house to hear.
They will continue to hire the cream of the crap because that is all that is willing to come here and be abused by this company. When it takes months of negotiating just to convince a company to try to treat an employee half way decently during a family emergency; that should be telling enough for any possible new hires about life here.
