Maybe I've been especially fortunate, or I'm just not understanding the question right, but I've felt respected pretty much from the beginning of my career (aside from grad school, which was not great, in many respects). Or at least I've felt "treated with respect" -- not sure if that's exactly the same thing. But I've always been given a fair amount of independence at work, and I've generally been able to solve whatever I'm assigned to solve, or clearly articulate the challenges, allowing those with different/more expertise to help out. And I've never been made to feel ashamed or inadequate because of either the work I've completed or the work I've needed to seek out additional help to complete.
