Print Friendly, PDF & Email

The deadline to file retroactive chronic mental stress claims is July 1, 2018.

Information regarding the new chronic mental stress policy has been posted on the OPSEU website, (view it here), however, below is a summary of this important information:

The Workplace Safety and Insurance Act (WSIA) was amended to include entitlement to work-related chronic mental stress.

WSIB’s Chronic Mental Stress policy states that a work-related chronic mental stress must arise from a substantial work-related stressor (other than decisions/actions that are part of the employment functions (such as terminations, demotions, transfers, discipline, etc.).

Although the new policy will apply to all accidents on/after January 1, 2018, there is also a transitional provision for work-related chronic mental stress conditions that occurred between April 29, 2014 and December 31, 2017. The deadline to file a claim for the aforementioned period is July 1, 2018.

To be eligible for entitlement under the Chronic Mental Stress policy, the following conditions must be met:

  1. An appropriate health professional has provided a diagnosis of work-related chronic mental stress based on the Diagnostic and Statistical Manual of Mental Disorders (DSM),
  2. A worker has experienced a substantial work-related stressor/s, like ( but not limited) to workplace bullying or harassment
  3. The substantial work-related stressor/s was the predominant cause of the work-related chronic mental stress

Workers who already have mental stress claims pending at WSIB or WSIAT will have their claims reconsidered by the WSIB. Please contact WSIB to inquire on the status of the previously filed claim.

Please share this information with all members possibly affected by these changes to the Workplace Safety and Insurance Act.
