National Master Freight Agreement...... article 16 section 4 reads "Employees shall immediately, or at the end of their shift, report all defects of equipment." Inspections by the way are required by law. Last week we were short on empty trailers. Linehaul brought St. paul 4 empty trailers. We put 3 of them out of service. The linehaul drivers did not perform a pretrip inspection or ignored the defects pulling these trailers here. They did not perform a post trip inspection either. Do these drivers care? Does the company care? No disciplinary action has been taken.
