When someone makes a mistake, that's an incredible investment in them. I'm always surprised* when people try to throw it away by firing them or making them want to quit. Help them learn from it and apply that knowledge moving forward. Otherwise they're just taking that knowledge and using it to help another company.

*Obviously with the caveat that some people are repeat offenders who are careless or just not good employees

In other professions some mistakes cost the professional real money (doctor malpractice) or cause them to lose their license (drinking and driving with a commercial vehicle license).

As an industry we don't have a response to a truly neglectful mistake yet.
