> Don't bitch, or moan, or rub it in if things go wrong. Chain of command. One of these days you'll be there too.

No I don't think it's how it works at all. If you want to show value you should absolutely point out you were right.

There's always time for lessons learned, but gloating isn't mature or helpful.

Honestly, I've never stuck around with a bad boss long enough to get into this sort of situation with them. Life is too short.

Most managers I've had a long-term relationship with have been, at worst, overwhelmed or utterly beholden to bad priorities set further up the chain. They all have been decent enough folks, trying to do their best for the organisation.

You gotta spend all your time with these people. Rubbing your correctness in their face ain't going to make either of your work lives better.

Try doing the same with your partner, see how that goes.
