Just Culture makes the entire operation safer, we follow the same practice up here. It means that the prospect of turning yourself in doesn't mean any reprocussions, unless of course it's a constant repeat offense, in which case that person would probably realize they shouldn't be in the job any more.
Having an OI or a "deal" as the NATCA boys and girls call it, is probably one of the worst feelings in the world, even though 95% of them there was no imminent danger, which is why we're so anal on the frequency about a lot of things most pilots would think is no big deal.
Even when you're 99% sure the pilot messed up and caused one, you feel like complete and utter crap until the tapes are pulled and reviewed, and even then you sit there and analyse it for hours and days wondering if you could have done something different.
The minute stressors about this job making sure everything is checked and cross checked, and re checked, constantly at 100 miles a minute, is what makes this job difficult for most people, not the prospect about welding metal together...
