That said - to the question about unicorns: You're always expendable. Same as any job - same politics - same nonsense. No matter how important they make you think you are to a products success - they'll fire you regardless. It's amazing how fake management will be about urgency. "This is the most critical business function! We must have people working on it!11!!1!1!" Fires key employee because they didn't like them - "critical business function" gets shoved into the backlog to never be seen again. People are fake and think they need to show urgency to get the most value out of their employees.
