> If it's a senior developer, then they should feel comfortable speaking up when there's a disconnect or misunderstanding. I would argue that one trait is the overwhelming majority of what separates a senior developer from a junior one.

Whether seniors feel confident to correct the manager depends primary on how manager acts when corrected. There are many managers who don't get corrected by seniors and seniors who do learn not to do that - either becabuse it is useless or will be punished.

Either way, juniors do talk with management fairly often, whether they have responsibility or not.
