Pees in the brown Koolaid
While it is true that UPS is much more strict in determining fault than the police, there will always be situations that are truly unavoidable. The problem with the stance that your DM is taking is that it is possible to get fired for having too many avoidable accidents, so classifying every accident as avoidable, whether valid or not, may prove to be an issue in your center over time.
The company can "charge" you with an accident any time they want to... whether there was an accident or not, whether you were at fault or not. Safe driving awards are not contractually required.
The fun starts when the "avoidable" accidents lead to disciplinary action and the grievance procedure kicks in. At that point, each "accident" can be evaluated on its individual merits as to whether or not disciplinary action is truly justified.
