Chronic conditions and work
Chronic conditions refer to diseases and health conditions that last a long time and generally progress slowly. Although they can occur at any age, they become more common later in life. They are often invisible, sometimes episodic (i.e. they come and go) and often characterized by fluctuating symptoms that leave people disabled one day and functional the next. Examples of chronic diseases include arthritis, diabetes, chronic pain, depression and fibromyalgia. IWH research in this area focuses on the effects of chronic disease on work participation and productivity, as well as the effectiveness of job accommodations, benefits and other programs to ensure workers with chronic disease can stay at, or return to, work.

What do workplaces need to know to help older workers stay on the job? A qualitative study of older workers’ disclosure decisions
Historic labour shortages are affecting every Canadian job sector. Many workers aged 50 years or more want to work longer, often beyond the traditional retirement age. However, we understand little about the different workplace support needs they may have and whether workers choose to share their needs with others—especially given the negative stereotypes that often surround older workers. In this presentation, Dr. Monique Gignac shares insights from her study on older workers’ workplace support needs and disclosure decisions. She highlights how workplaces can help older workers stay on the job, regardless of whether they disclose their needs.

Examining the link between job insecurity, work limitations and persistent symptoms among young adults with rheumatic disease
Young adults with rheumatic disease who reported high work activity limitations were also more likely to report persistent high levels of pain, fatigue and active rheumatic disease symptoms. Those who experienced job insecurity were more likely to report persistent pain and active disease symptoms. That's according to an IWH follow-up study conducted over 27 months.
