There really needs to be a Portfolio Management Team (PMT) that schedules the projects. They really need to police this situation. The managers will never be able to do this on their own because they are being rated on how well they deliver their projects. This is a common problem and can only be reconciled when a very senior manage steps in to direct change.
I will tell you that my experience has been when a company make this change and manages the pipeline the results can be fantastic.
