Coworker’s cane-shortening prank covered by workers’ compensation

In an unpublished decision, the California Court of Appeal ruled that workers’ compensation was the exclusive remedy for a worker’s injuries resulting from a prank at work. A worker was using a cane while recovering from a knee injury. He was trying to wean himself from using the cane and left it at his desk when he walked away briefly. When he next used the cane, he lunged forward and reinjured his knee.
