The basis for a good team is trust.
Team members who trust each other have positive expectations of each other. This is a great underpinning for resolving conflicts and discussing problems.
Simon Sinek talks about trust and leadership in his TED talk Why Good Leaders Make You Feel Safe.
So, how do we create a culture of trust? The basis is not that difficult: make the decision yourself to trust. Model and share this with your team. When making decisions yourself and with your team, reflect on whether those decisions agree with your value of trust.
So, as Simon says:
What I learned was that it’s the environment, and if you get the environment right, every single one of us has the capacity to do these remarkable things, and more importantly, others have that capacity, too.
You see, if the conditions are wrong, we are forced to expend our own time and energy to protect ourselves from each other, and that inherently weakens the organization. When we feel safe inside the organization, we will naturally combine our talents and our strengths and work tirelessly to face the dangers outside and seize the opportunities.
