Seriously?
Union members cannot be required to inform/provide statements on other members. It rarely happens but you can be brought before your local's e-board and expelled from your local for doing so.
If you do this, you're a rat. If someone is stupid enough not to report an accident, then the company is going to eventually catch them. UPS has LP supervisors and other goons on their payroll for a reason.
