I wouldn’t say “always.” Also, trust isn’t binary: it’s earned and varies. You usually wouldn’t give a new employee sole, unrestricted access to megadollars and you wouldn’t micromanage microtransactions of a 10 year manager. Delegate with risk management, e.g., common-sense. If a person starts making big mistakes, then you take non-nuclear corrective actions/find out what’s going on. On the other side, if someone improves, reinforcing actions are possible.
