Shouldn’t management be able to identify that their team is comprised of these otherwise incompetent individuals? I see those 2am emails as a symptom rather than a catalyst.
But for a company like Google, nowhere near an existential threat, it makes sense to prioritize long term players capable of delivering for years.
Should probably restrict this to companies that had revenue and paid its employees.
There is no way around it for borderline employees too. Assuming these studies are correct, what the heroic effort for borderline employee do is signaling desperation and emotional investment.
Even then you'll still get "just this once" people who understrand the problem but can't help themselves.
