Nice thought but I would guess that a fairly large percentage of them agree with management.
Got to remember that most of these engineers graduated from the political indoctrination centers we euphemistically call colleges.
...but a lot of men in STEM fields are the ones that are more conservative.
That said, this is California, where you’d BETTER comply with group think. Going to another company may not be any different. I work for a Silicon Valley tech firm, the work force is not concentrated there though (I’m not there), so I don’t see this in general. I do notice though that MANY of my colleagues from CA are quick to assume everyone thinks like them (anti-Trump).
It’s as though there’s some sort of magic spell they’re all under. I always thought people would see obvious propaganda and laugh. It seems that more subtle propaganda, that is 24/7 and everywhere, is more influential than I ever would have thought. It’s like asking, how many in North Korea actually believe the BS? You’d think none, but you’d be risking your life to not play along - at what point do you convince yourself it must all be correct if only out of the need for self preservation?
