except it isn't
the principle is "have backbone; disagree and commit"
there's checks and balances in the principle's words themself. every leader i've had who has "disagree and commit" as their guiding light has just been an autocrat. they never mention on the "have backbone" part.
i had a VPE from BigCos come into a LittleBigCo. he was all about "disagree and commit"
really, he had a nose for dissent. he went around managers who disagreed with him to corral their engineers to his side. he put near-founding engineers on bad projects to force them out.
i tried to have backbone with this guy once. i thought one of his tech decisions was bad (and in reality it was politically motivated to force people out.) i wasn't rude or anything. he had a 1-on-1 call with me, and acted like i was being irrational. i stood my ground and made fact-based arguments. he was losing the 1-on-1 debate, so how did he close it?
"look whateveracct..i just have this crystal ball in my stomach, and it's usually right"
disagree and commit? more like stfu i'm the boss
