The best way for a team to thrive is to have a good, solid culture to work in. How could that look like?
Words like respect, honesty, encouragement, trust, empathy, integrity, no gossip, accountable, productive, ethical, supportive, …, etc. are key in a such a culture. Maybe you can add your own words to it.
When you build the culture, or are part of establishing it, ask yourself: do I want to be part of a team working with a culture like that?
