A worker employed by Employer A slipped on a heave in the asphalt in the yard of Employer B, injuring his knee. His workers’ comp claim was approved and charged to Employer A’s account. But Employer A appealed, arguing that Employer B should be charged because its negligence caused the injury. The Appeals Commission rejected Employer A’s argument. Employer A didn’t investigate the scene of the worker’s incident or notify Employer B until two and a half years later, when it was too late for Employer B to conduct its own investigation. Thus, there was insufficient evidence that Employer B was negligent and so should bear the costs of the injuries, concluded the Commission [Decision No.: 2014-1109,  CanLII 5714 (AB WCAC), Feb. 4, 2015].
