I have fibromyalgia, which causes me to have migraine headaches and pain, particularly in my neck and upper body. My pain level varies, but it is severe on occasion. I have told my manager and asked for an accommodation, but he only makes light of my condition, saying things like "everyone gets headaches," or "no pain, no gain." Doesn't my employer have a duty to provide reasonable accommodation?
Whether your employer has to provide a reasonable accommodation depends on two things: whether you have a disability, and whether the modifications you need would create an undue hardship for your employer.
The Americans with Disabilities Act (ADA) defines a disability as a mental or physical impairment that substantially limits a major life activity (such as walking, sleeping, or caring for oneself) or a major bodily function. Rather than providing a list of conditions that are considered disabilities, the ADA instructs employers (and courts, if it comes to that) to look at how the employee's condition affects his or her functioning. Because the symptoms and severity of fibromyalgia can vary, some people who have fibromyalgia may not be considered to have a disability as legally defined. However, recent amendments to the ADA make clear that Congress wants courts to err on the side of inclusion, allowing as many people to be covered by the law as possible.
Assuming you have a disability, the next question is whether accommodating you would create undue hardship for your employer. An employer doesn't have to provide a reasonable accommodation that would involve significant expense or difficulty, considering the size, resources, and type of business of the employer. For the symptoms you are experiencing, potential accommodations might include:
(You can find many more accommodation ideas at the Job Accommodation Network's page on fibromyalgia accommodations.) Of course, the precise accommodations you need will depend on your job and your symptoms. As you can see from the list above, however, effective reasonable accommodations need not be particularly costly or disruptive. Even the smallest employer can afford a computer glare screen and non-fluorescent lighting!
Restart the process with your manager by putting your disability and your request for an accommodation in writing. (For a sample letter and tips for writing your own, see Requesting a Reasonable Accommodation). If your manager doesn't take you seriously, move up the chain of command. If your company has a human resources department, give them a copy of your request as well. Even keeping in mind that many people aren't aware of how painful and debilitating fibromyalgia can be, your manager's comments might be characterized as harassment based on your disability, particularly if they persist after you clearly point out your condition and limitations.
