Also, I'm pretty sure I've said this before, but I'll say it again:

Part of your job as a senior is to tell your juniors about your fuckups. The embarrassing cringe reckless and lazy bullshit that you did when you were new, and the various times you brought down Prod. We ALL did it sometime. And then tell them: the moment you realized you fucked up, I know, the impulse is to try and cover it up, but don't do it. Come to the seniors you trust, and they'll help you unfuck it, and fight management tooth and claw like mamma and pappa bears to defend you from any shitheads in management. Because that's what our seniors did to us.

@JessTheUnstill I have lost count of the number of times I've said:
- I've made that mistake before
- That's a good question, I have no idea, lets find out together

Oh, and more than a couple of times I've ran interference (creative truth telling) when a junior made a boo-boo so that they can get on with fixing the thing. And yes, the team then made changes to work instructions so that the mistake was much less likely to be repeated.

Seniors are not all-knowing (okay, maybe that's just me...) and I try to normalise the not-knowing-but-knowing-how-to-find-out and my other job is getting others to the point that I'm replaceable.
