Scheduled maintenance - Thursday, July 12 at 5:00 PM EDT
We expect this update to take about an hour. Access to this website will be unavailable during this time.
Products are ordered online and shipped immediately from anywhere in the world. There are 24-hour restaurants, manufacturing plants, and call centres that never close. We live in a global economy that requires products and services to be delivered around the clock. As a side effect, many workers are exposed to the strains and health effects that come with working at all hours of the day and night. Changing schedules can make it difficult to ever fully adapt. There is no doubt that shift work can have negative effects on workers' personal health and safety.
About shift work
Work that is scheduled outside "normal" daylight hours (i.e. 9 am to 5 pm) is called "shift work". Shift work schedules can vary from one workplace to another and workers may rotate through shifts or remain on a single shift (for example, permanent nights).
Shift work is a reality for about 25% of the North American working population and with more occupations and industries operating around the clock, this number is not likely to decrease. The growing numbers of shift workers include those in healthcare, railways, road work, manufacturing, just-in-time industries, trucking, security, emergency services, customs and immigration, public utilities, seasonal occupations, the military, gas stations, grocery stores, and restaurants.
Circadian rhythms are our body's biological clocks that manage various internal functions throughout a 24-hour day, using daylight and darkness as cues. Working during the night and sleeping during the day is contrary to our natural rhythm. This is what can make sleeping difficult for shift workers and can mean that the body cannot recover as quickly from physical and mental activity during these "opposite" hours.
Here are some key risks associated with shift work:
Studies have shown that shifting schedules increases injury risk. A recent study found that not only do evening-shift and night shift workers have a higher injury risk than that of daytime workers, but workers are even more at risk when they switch between shift schedules.
Tips for employers
Tips for shift workers
There are steps that shift workers can take with their diet, sleep and social life to help preserve their health.
Along with the advantages of schedule flexibility, shift work brings health and safety risks associated with working 'non-traditional' and rotating hours. Recognizing and taking steps toward minimizing these risks can be beneficial to both workers and employers.
Tips & Tools
Martin finally wandered into the office almost an hour late and slumped into his seat. He didn't offer a reason. He just put his head set on and turned towards his computer. His manager noticed that Martin was quieter and more withdrawn than usual, and was having difficulty completing simple tasks. While this behaviour was previously unusual for Martin, it was beginning to become a pattern.
Martin is not alone. According to the Canadian Mental Health Association, 20% of Canadians will experience a form of mental illness at some point in their lifetime. A healthy Canadian economy - and a psychologically healthy workplace - relies on healthy minds.
A psychologically safe and healthy workplace promotes emotional well-being, and presents minimal risk to employee mental health. By making changes to your work environment, and offering support to employees, you can reduce the occurrence, duration and severity of mental illness, and enhance recovery. So how do we do that?
There is no one "right way" to create a mentally healthy workplace. Every workplace is different from the size of the organization, to the people doing the work, the work that needs to be done, and the leaders of the organization. All of these factors play a role in employee mental health. However, businesses can create and nurture a psychologically healthy workplace by including mental health in their business plan. Poor mental health not only hurts the individual, it also reduces corporate profits. It's important that all levels of the workplace - including the Board of Directors, management, finance, and human resources departments - get involved to incorporate mental health in the workplace.
Here are three things you can do to foster a psychologically safe and healthy workplace:
1. Create and implement a Comprehensive Workplace Health and Safety Program.
This program is a series of strategies and related activities, initiatives and policies developed by the employer, in consultation with employees, to continually improve or maintain the quality of working life, health, and the well-being of the workforce. These activities are developed as part of a continual improvement process to improve the work environment (physical, psychosocial, organizational, economic), and to increase personal empowerment and personal growth.
2. Commit to creating a workplace that promotes mental well-being.
It is essential to have strong and clear senior leadership and the meaningful involvement of leaders in the development of a mental health program. Organizational commitment is crucial. All levels of the organization play a role in designing, implementing, monitoring, and reviewing policies or practices. Form a corporate wellness working group with representation from senior management, employees, trade unions, human resources, and occupational health and wellness experts to lead this initiative.
3. Educate and train each member of the organization (managers, supervisors, employees and health and safety committee members) about the importance of mental health in the workplace. Provide education and training that ensures managers and employees know how to recognize hazards such as harassment, bullying, and psychologically unhealthy work conditions. This training provides concrete ways for co-workers to recognize and talk about mental health issues in general. Managers can additionally contribute to a positive work environment if they have the skills and knowledge to identify and respond to issues before they escalate.

Mental Health: Awareness, free e-course
It is generally believed that some stress is okay ("positive stress") but when the level of stress is greater than you can handle, both mental and physical changes may occur. Factors in the workplace can cause, contribute to, or worsen our mental distress, which may affect our physical or mental health. Stress is also an important issue for employers who realize that when workers are not well, the business is affected.
CCOHS worked with the Occupational Health Clinics for Ontario Workers (OHCOW) to develop a free smartphone application (app) which allows you to answer the Copenhagen Psychosocial Questionnaire (COPSOQ) and measure your level of stress.
After starting the app, you are asked to respond to 25 questions about work demands, organizational factors, relationships, workplace values, health and safety concerns, stress symptoms and offensive behaviours. On the results page, each item is scored in comparison to a reference population so you can compare. For items where your score is worse than the reference population, you can click on an icon that takes you to some ideas on dealing with that particular factor.
The original Copenhagen Psychosocial Questionnaire was designed to be done collectively and analyzed on a group basis. This individually scored version lets you get a feel for what is in the survey as well as provides ideas on how to improve your workplace psychosocial conditions.
The app is available under OHCOW's name from the Apple App Store for iOS devices and Google Play store for Android devices. A BlackBerry version of the app is coming soon.

Workplace Health & Safety Matters
Workplace Health and Safety Matters is the blog of Steve Horvath, President and CEO of the Canadian Centre for Occupational Health and Safety. In a recent blog post, Steve shares his thoughts on the 25th anniversary of the Occupational Health Clinics for Ontario Workers (OHCOW) and the launch of their new smartphone app.
Recently, I had the honour of celebrating the Occupational Health Clinics of Ontario Workers (OHCOW) 25th anniversary at their event "Celebrating the Past and Looking Forward". Our organizations have had a long-standing history of collaborating and sharing information and resources with the common goal to help Ontario workers stay safe on the job. I truly believe the synergy of our organizations has served workers successfully over the years.
To show our appreciation of our 20 year affiliation, I presented OHCOW with a plaque recognizing our partnership, and shared some of my personal thoughts and reflections of their organization. I believe each clinician; pioneer and tireless workplace safety advocate at OHCOW have provided our country with an immense amount of value. I especially saw this when CCHST hosted a delegation from China a few years ago. We introduced the group to the staff at OHCOW and after reviewing their operations, the delegates returned to Chongqing and built a workers' health clinic inspired by what they saw at the OHCOW offices. Now, tens of thousands of workers are receiving clinical services and counseling for occupational issues as a result of the OHCOW model.
Another reason to celebrate OHCOW
The event marked the official launch of the "Mental Injury Toolkit (MIT)" and the "Measure Workplace Stress App". This special project was a collaborative effort between OHCOW and CCOHS to build a new smartphone application that provides a set of tools for workers to measure their level of workplace stress. It will also correlate the worker response input, highlight issues for focus, and provide direction for obtaining more information.
Congratulations to OHCOW on 25 years of commitment and caring and making a difference in the quality of Ontario workers' lives.
