After 20+ years in tech, the only time I have ever seen a developer fired for making a mistake was when he leaked credentials because he used one of our repos as the base for an interview project at another company (on a day when he was allegedly working from home). We had a hardcoded key in our package.json to allow it to access a private repo, and he pushed that to a public repo which had an incriminating name like company-x-interview-project-hisname. We immediately got an email from Github because they scan for such things. We rotated our keys within a few minutes, and he was gone the next day. Obviously we should have been more careful with our keys, so all would have been forgiven if not for the fact that he leaked keys while looking for another job on company time.
