As an Over-All Project Manager I usually check all their logs first thing first. Then check my TLs in regards with their groups' stat as well as their groups works. Randomly check how TLs' check their members leads and how they coach them.
Being their PM, I've learned that giving an open communication with everyone is a big KEY towards successful project and that managing everyone fairly by applying all the rules is a big factor for it will help them to understand that your decision is not one that can be easily break.
Can work anytime you want.
