Working can be physically demanding when you have a chronic illness like rheumatoid arthritis (RA). As a person with a chronic illness or disability, you are entitled to workplace accommodations under the Americans with Disabilities Act (ADA). Accommodations are adjustments to the way you work so you can do your job. In other words, changing how you work, but not the goal. These types of adjustments can involve equipment or flexibility in how you work, or both.
