You may build relationships with people you work closely with. I've certainly done that at multiple workplaces.
However, that doesn't mean anything when someone whom you've never even spoken to decides shareholders need 0.5% more profit and you gotta go.
That being said, I strongly believe that it's never wise to find fulfillment solely—or even primarily—in vocation. Absolutely try to build a career that is life-giving, but there is so much joy and meaning to be found outside of work. We thrive in community.
