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.

Is precarious work more prevalent for people with disabilities? The role of age and job tenure

Workers with disabilities are no more likely than those without to work in precarious jobs. However, some subsets of people with disabilities are more likely to work in precarious jobs—older people or people with shorter job tenure. Contrary to expectation, younger people with disabilities are not more likely than older people with disabilities to have precarious jobs. Among people with and without disabilities, having better health is linked to a lower likelihood of working in precarious jobs.

Does it matter what workers’ reasons are for disclosing or not disclosing a disability at work? Why and how?

Deciding whether or not to disclose a disability to others at work is a complex consideration. People with many chronic mental and physical health conditions, often called episodic disabilities, experience times of relative wellness punctuated by intermittent periods of activity limitations. How do they decide whether or not to disclose their health conditions? In this presentation, Dr. Monique Gignac shares findings from her study examining participants' reasons and goals for disclosing—and whether these matter to work support outcomes.
