I've worked at a place like you describe. Supportive team, cooperation, understanding, etc. Despite whatever disagreements it was pretty great. For about 2 years. Then the stuff like irrational business decisions, difficulty getting people on board to address issues, all this institutional inertia, people saying no to everything that could possibly improve things internally. It weighed down so much that I just couldn't handle working there anymore.
