Building trust is a gradual thing. You give some, you get some, you do that long enough and you will have a lot of trust. You can still lose it all in a heartbeat. But you're never going to get the keys to the kingdom on day #1.

I always tell juniors that even if their company doesn't have an explicit probationary period, they should assume their behavior and results are being carefully monitored for the first year to watch for signs of a bad hire.
Hiring someone is never equivalent to having full trust in them. Reputations don't start at 100% on day 1, they start as a neutral value that you need to build up over time. You also need to avoid breaking it down. It's much faster to destroy a reputation than build it up.
