Then how do you expect to work together?
If you can’t trust the person beside you, in front of you or behind you to be there when you need them the most.
Then how can you lead them?
You need to know that when you ask for their help they will be there for you, or when the workload is too heavy they will all chip in to help or when it comes down to do their review they will know that you have their best interests at heart even when the news is sour.
You can’t do any of that without trusting your team.
And they can’t do the same if they don’t trust you to be there for them.
