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.

Deciding whether to share health information at work: A new evidence-based tool for workers with chronic conditions
Workers with chronic and episodic physical and mental health conditions often struggle when deciding whether to seek support from their workplace. In making decisions, they weigh risks like the loss of privacy or reputation if they disclose their needs, versus concerns about job difficulties and work performance if they don’t receive support.
In this presentation, Dr. Monique Gignac focuses on the challenges inherent in the decision-making process. She also describes a new decision-support tool called DCIDE that aims to help workers navigate the complexity of disclosure decisions. Developed as part of a large research partnership with input from researchers, people with lived experiences, and health charities, DCIDE is an online, interactive tool that guides users through disclosure decisions and links them with additional resources to support their disclosure and privacy preferences.
