one employer had the quite silly but effective plan where they "billed" managers for meetings. whenever there was a meeting everyone who was there basically got to invoice the department for the time lost.
meetings became exceptionally short and to the point
@icedquinn I used the same strategy in a retail store. If other managers pulled my people, I had personnel transfer their hours. When store manager told me to stop, I said no because the lost productivity reduced my bonus. He told everyone to leave my people alone.
