A custodian started work at a new school that required more mopping. After her hands started to fall asleep and go numb, she filed a workers’ comp claim for bilateral carpal tunnel syndrome, which was denied. But the Tribunal ruled that her condition was covered by workers’ comp. Based on the testimony, her job description, the medical evidence and common sense, the Tribunal concluded that it was at least as likely as not that the worker’s condition arose out of and in the course of her employment [Re. 2011-633-AD,  CanLII 25460 (NS WCAT), May 7, 2012].
