> I've heard tales of 300k/yr engineers that just sit there and wait for a manager to ask if they're blocked, or just sit there until they're told what to do.
This is widely presumed to reflect reality within a 1-2 degrees of separation from myself as well as from many of the people I speak to. Part of the problem is that there is always plausible deniability. Like the adage of how unwise it is to fire custodians just because you never see a mess and therefore you never actually see the custodians do anything, it may be "unwise" to lose the presence of these 300k/yr engineers just because they somehow actually keep things going smoothly.
> I constantly reiterate to people, whether they're reporting to me or not, that they need to speak up when there's a blocker.
This is presuming a particular/healthy culture where open communication is valued, appreciated, and not punished. This is not always the case, and an "objective description of a blocker" could result in some bruised egos where it transforms into blame upon some person or team for being or causing the blocker. People who experienced these cultures may be waiting for private conversations (such as 1-on-1s) that minimizes the risk, and they may be waiting to identify you (or whomever they are talking to) as a person who could make communicate the nature of the blockage in a politically favorable or neutral manner. All of this may be happening without the people involved consciously aware of this behavior of pushing out information through private conversations. And this maintains plausible deniability for ALL parties. The person who is blocked is never identified. The person who may have been the blocker is never identified. And hopefully everything gets fixed before anything is actually worth escalating.
