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.

Gender differences in the impact of eldercare on work

Women are much more likely than men to stop working, to work part time and to temporarily take time off work in order to care for an older relative. These differences are seen even after taking into account factors such as marital status, having children, hours of work, pay level, job tenure, and status as main wage earner in the household.
