Transparency in a team definitely builds trust. If everything is transparent in the team, the trust with one another will increase.
Let go even if that is one team member’s mistake. Stop blaming. Support the person altogether as a team. Work on correcting the mistake. This is one of the best ways to build trust.
See mistakes as opportunities. Learn what to do and what not to do. Don’t just see the employees in their triumphs alone. Look at the mistakes too as chances to find better things, Next time your team member makes mistakes, learn from it. Support them.
Don’t control and operate your team by sitting inside your room. Team dynamics are not about that. Spend time with your team.
