>No second chances, ever.

I find this to be an unrealistic standard. We all have lapses given the right moment (attention, tiredness, distraction). The question is do people comprehend the problem and are willing to work on it/ adjust for it?

Differently put, the issue isnt just one of detecting problems but detecting those that cant be fixed/adjusted for. Which means putting resources into debugging how they appear for which reasons. Seeing as walking away is costly, that can often be a worth while investment.

This is less about trusting and more about valuing functioning team relationships. Benefit of the doubt is a good strategy for team building, at the very least for information gathering.
