Introduction: Worker Call to Action

Part 1 — Why Should We Care?

Workers and employers are busy enough, so why should anyone take action to deal with either the causes of or effects of workplace stress? Well, workers care because workplace factors can cause, contribute to, or worsen our mental distress, which may affect our physical or mental health. Employers care because they want their workers to be well, because when workers are not well the business is affected.

Part 2 — “Workplace Stress”: Assumptions, Terminology, and Approaches

What does workplace stress mean? Let’s clarify some assumptions, words, and approaches to workplace stress.

Part 3 — What Are Other Jurisdictions Doing?

There is growing attention on addressing workplace stress in Canada and across the world.

Part 4 — What Are My Rights And Legal Protections? (Focus on Ontario)

In general, legal protections for workers fall into four broad areas, fair treatment at work, protection of health and safety, duty to accommodate and income replacement.

Part 5 — Workplace Action Plan

Work and workers are all different, but no matter how different they are, it is possible for workers to take some steps to understand and address the causes of mental distress at work. This section provides a worker, JHSC or Union with tools to address the prevention of mental injuries in their workplaces.

These tools are not clinical diagnostic tools. They are not meant to diagnose medical or psychological conditions or to be used by a physician to these ends. These tools are designed to identify problems that may exist within the workplace and provide possible avenues to address them.

This resource kit and tools are provided with a focus on the Ontario jurisdiction – workers in other provinces or in federally regulated workplaces should refer to their own legal framework.
