    I don't think the engineer in the OP did a good job. They were the last link in the knowledge chain. It's on them to pass the knowledge along and onboard the newbies.

I find it weird that you’re blaming the Engineer and not the managers or culture. Isn’t it on them to make sure that knowledge is passed as well?

That's forcing the engineer to do what they should be doing. You can blame them for not doing that but that doesn't absolve the engineer of not doing what they should be doing.
