How many complaints do you then get through the hotline and those other mechanisms? Sometimes when people are employees of some system, it takes an awful lot of courage to complain about something or to find a culture of acceptance. They often want to keep their heads down, be the round peg in the round hole, and not disturb the water, because they'd like to keep their jobs. If they become a disturbance, they often end up with lower performance evaluation reports and they're out the door.
Do you have statistics on any of those things?
