The worker, a carpenter, appealed a Case Manager's decision denying entitlement for Traumatic Mental Stress (TMS) and Chronic Mental Stress (CMS) following a workplace altercation.
The worker alleged he was threatened and shoved by a co-worker and the project manager after raising safety concerns and supporting a unionization attempt.
The Appeals Resolution Officer found that the incident did not meet the threshold for an objectively traumatic event involving physical violence or a life-threatening situation, denying the TMS claim.
However, the Officer found that the co-worker's aggressive conduct, which included profanities and poking the worker in the chest, amounted to workplace harassment and was the predominant cause of the worker's diagnosed posttraumatic stress disorder.
The appeal was allowed in part, granting entitlement for CMS.
