Yup, another similar situation here - ~20 years in Bay Area, almost 15 years at one company, no one in my "network" said anything about jobs. I did contact a few directly and "not hiring right now". A bunch of others (since I was one of the younger ones at this company when I joined in '08) had since retired.

Got a new job through a LinkedIn ad, found a former co-worker here.

I mean, it could be that I'm not a great networking person, but.. I'll agree that network hasn't helped me much so far.
