i agree
so give a financial incentive to self-report. that discretion and confidence will be maintained. that graceful financial transition would be supported. because the company would rather deal with that, much cheaper than a PR fiasco, lawsuits, destroyed equipment, etc
enforce that approach by law even
then you are left with the truly deep in denial types. those who think they can beat their illness, or that continuing in their job is proof they have things under control, until they don't. these are people who might have even been attracted to the job of airplane pilot in the first place, as a proof to themselves they can maintain great responsibility in the face of stress
so the problem becomes one like pedophiles in the priesthood: in some ways, the priesthood attracts well-meaning individuals who think the religious purity will allow them to beat an affliction they know they have. of course, human weakness prevails in the end
or pedophile teachers
or sadistic cops: you know you get a thrill abusing and dominating, so you're attracted to the police force
these are difficult problems
but that doesn't mean we tolerate pedophile priests/ teachers, sadistic police, or mentally ill pilots. it just means it is hard to root them out when they have an incentive to hide
