A new tool to help workers make health disclosure decision

Workers with chronic or episodic health conditions may face the decision of whether to disclose their health information at work. But many find this decision challenging and stressful. A worker may need supports due to their condition but may worry that sharing health information could impact their reputation or job security. A new IWH tool, called DCIDE, was developed to help workers make these hard decisions.

Meeting on newcomer workers’ health inspires ideas for research and collaboration

Newcomer workers have a higher risk getting injured or ill at work than Canadian-born workers. In a step to address this longstanding issue, IWH recently hosted over 50 stakeholders to discuss the health and safety challenges these workers face. They also discussed how employers and others are addressing these challenges, and what research is needed to better support these workers.

Cannabis use by workers before and after legalization in Canada

On October 17, 2018, the non-medical use of cannabis was legalized in Canada. To examine the implications of this change for workplaces, the Institute for Work & Health (IWH) embarked on two research projects. The studies explored changes in cannabis consumption habits among workers; changes in their perceptions about such consumption; associations between cannabis consumption and occupational injury risks; as well as the use of cannabis to treat symptoms in the aftermath of a work-related injury/illness. This Issue Briefing provides an overview of findings from these two studies and the potential implications of this research for employers and policy-makers.

Which workers and jobs will be most affected by machine learning?

Machine learning is being adopted by more and more Canadian workplaces. Given this technology’s ability to learn, adapt and generate work outputs, it also has the potential to perform job tasks in place of humans. But which workers might be most affected by the use of machine learning? An IWH study explores this question.

Consultants play key role in OHS implementation at small firms

Time and resource constraints may make it hard for small businesses to access health and safety support programs. But, as an IWH study finds, small businesses gain from even limited participation in such programs. The study, based on interviews with small businesses that took part in Ontario's Health and Safety Excellence Program, also highlights factors that contribute to their success in the program.

Which workers use active forms of transportation in their commutes?

Walking, biking, or taking public transportation to work is one way workers can increase their physical activity. But does the choice to use active transportation differ for workers in different jobs, or between men and women? This study aimed to find out.

In which occupations are Ontario workers who had a work-related injury most at risk of opioid-related harms?

Formerly injured workers in certain occupations are at an elevated risk of experiencing opioid-related harms, according to a study by IWH and the Occupational Cancer Research Centre. Looking within a large sample of formerly injured Ontario workers, occupational groups with greater risks of harms included construction, forestry and logging, materials handling, and processing.

Workplace supports buffer productivity impacts of rheumatic diseases and depression

Young adults who live with both a rheumatic disease and depression have lower productivity than those who have only one or neither condition. That’s according to a new IWH study. Findings from this small study also suggest that having a supportive working environment can buffer the lost productivity issues.

Higher risk of work injuries found among those in precarious jobs: IWH study

Workers in jobs where precarious employment conditions are more common are more likely to experience a work-related injury or illness in Ontario, including COVID-19. That’s according to a pair of studies authored by Institute for Work & Health (IWH) researchers that examined whether employment conditions—for example, temporary contracts, involuntary part-time hours, irregular schedules and low wages—may be linked to the rate of work injuries.

Rates of work injuries have declined in Ontario, except the most severe

Past research in occupational health and safety, including studies conducted at IWH, has shown a general decline in rates of work-related injuries in Ontario over the past two decades. But a new IWH study, based on emergency department records from 2004 to 2017, shows that when it comes to very severe injuries, no such decline was seen among men. It also finds an increase of 18 per cent among women.

Working unpaid overtime linked with high stress and burnout: IWH study

Building on research linking overtime work to depression, anxiety, and other mental health concerns, an IWH study investigated how working unpaid overtime is associated with mental health in Canada’s working population. They found that that the more unpaid overtime hours worked, the more likely a worker is to report stress and burnout.

Exploring how workplace solutions can mitigate opioid harms among workers

With the recognition that workplaces can play a part in responding to North America’s opioid crisis, the OCRC and IWH brought together over 100 occupational health specialists, government representatives, union advocates, researchers, and others to discuss how to prevent opioid harms among workers. Presentations, panel discussions and breakout sessions provided a lot of food for thought about the way forward.

Workers who had a work-related injury have higher risk of opioid-related harms than the general population in Ontario

An IWH study examined how opioid harms in a large group of Ontario workers who had a work-related injury compared to harms in the general Ontario population. They found that the workers had higher risks of emergency department visits and hospitalizations for opioid-related harms. This pattern was seen across most occupations and industries within this group of workers.

How do employment support programs impact the health of young adults with episodic disabilities?

The unpredictable and often invisible nature of episodic disabilities can make it challenging for workers to find and sustain employment while managing their fluctuating symptoms and work demands. For young adults navigating early career phases, these challenges may also have life-long impacts on their career progression and health. Researchers on an IWH study set out to investigate whether employment support programs for young adults with episodic disabilities may also impact their health.

What can work-related COVID-19 cases tell us about how to prepare for the next pandemic?

To what extent did workplace exposures account for the transmission of the COVID-19 virus during the first two years of the pandemic? A new study by IWH combined data sources to estimate work-related infection rates, using a method that took into account major shifts in where people worked. It found the role of work exposure changed from wave to wave, in a dynamic pattern not in keeping with the number of cases in the general population.
