Growing a Team - No is the New Answer
Similar to accountability, trust is the backbone of growing a strong team, and is best produced when reciprocated.
A trusted leader, trusts their team.
With this comes communication - the so called cardiovascular system of a team.
A team full of yes people, afraid of holding each other accountable will always struggle to communicate openly about other issues.
Healthy discussion and the ability to respectfully question your peers, superiors, and subordinates not only creates a positive team dynamic, it results in more productive discussion.
