A worker was loading an excavator onto a float. A co-worker approached and told him to stop because what he was doing was unsafe. The worker told the co-worker to mind his own business and go back to his truck. The co-worker refused. The worker attacked him, striking him two or three times in the head and knocking him to the ground. The worker then kicked him in the head and body with his steel-toed work boot and stepped on his arm. The co-worker sustained permanent brain injuries. The worker was arrested and pleaded guilty to aggravated assault and two other charges. In sentencing the worker, the court noted that he’d intentionally caused serious injuries in an unprovoked assault upon a co-worker who had been acting out of concern for workplace safety. Given that he took responsibility and didn’t have a long criminal record, the court sentenced him to four years’ jail [R. v. Parker,  CanLII 64243 (NL PC), Oct. 15, 2013].
