You say that but there's a growing value in being able to tell it like it is. An example - I even saw the "ability to speak truth to power" appearing on an internal job advert earlier this week, so there's clearly an awakening about the value of hearing the reality of the situation.
I feel a shift coming in the next couple of years where the C-suite will realise the value in hearing what's happening on the ground rather than surrounding themselves with yes-men.
