A Psychologically safe workplace is effective when no one will be punished or humiliated for speaking up with ideas, questions, concerns, or mistakes.

Humiliation, blame, criticism, and bullying create workplaces where employees are filled with fear. This kind of psychologically unsafe environment doesn’t get the best out of people. Workers are too busy watching their own backs and frightened of putting a foot wrong to make suggestions and help each other out. They dare not share ideas for fear of being shut down, find themselves in trouble or in line for the next round of redundancies.

It doesn’t matter who is on your team.
They can be introverts or extroverts, friends, or enemies.
What matters is how they are allowed to interact.
Conversational turn-taking and ostentatious listening are key.
This will provide an environment that builds psychological safety.
