Not only is there collateral damage, but a complaint-based system takes a picture of the complaint at the time it was lodged. A situation is never static, but it takes years to settle a complaint. However, a proactive system makes it possible to address issues that may come up on an ongoing basis as salaries are reviewed. It is a lot more dynamic in terms of results, a lot less static, which leads to fewer confrontations and gives results more consistently than a complaint-based system.
