Accommodation and Compliance Series:
Employees with Chronic Fatigue Syndrome (CFS)

PDF DownloadPDF Version DOC DownloadDOC Version Audio Version


JAN’s Accommodation and Compliance Series is designed to help employers determine effective accommodations and comply with Title I of the Americans with Disabilities Act (ADA). Each publication in the series addresses a specific medical condition and provides information about the condition, ADA information, accommodation ideas, and resources for additional information.

The Accommodation and Compliance Series is a starting point in the accommodation process and may not address every situation. Accommodations should be made on a case by case basis, considering each employee’s individual limitations and accommodation needs. Employers are encouraged to contact JAN to discuss specific situations in more detail.

Information about Chronic Fatigue Syndrome (CFS)

How prevalent is CFS?

It is estimated that perhaps as many as half a million persons in the United States have a CFS-like condition (Centers for Disease Control and Prevention, 2012). Typically, women are diagnosed with CFS much more often than men, and it most commonly affects people in their 40s and 50s (Mayo Clinic Staff, 2014).

What is CFS?

In order to receive a diagnosis of CFS, a patient must satisfy two criteria. First, an individual must have severe chronic fatigue of six months or longer duration with other known medical conditions excluded by clinical diagnosis (Centers for Disease Control and Prevention, 2012). Second, an individual must concurrently have four or more of the following symptoms: substantial impairment in short-term memory or concentration; sore throat; tender lymph nodes; muscle pain; multi-joint pain without swelling or redness; headaches of a new type, pattern, or severity; unrefreshing sleep; and post-exertional malaise lasting more than 24 hours (Centers for Disease Control and Prevention, 2012).

What are the symptoms of CFS?

In addition to the primary defining symptoms of CFS, some CFS patients have reported a number of other symptoms. They include abdominal pain, alcohol intolerance, bloating, chest pain, chronic cough, diarrhea, dizziness, dry eyes or mouth, earaches, irregular heartbeat, jaw pain, morning stiffness, nausea, night sweats, photosensitivity, shortness of breath, skin sensations, tingling sensations, and weight loss. A majority of CFS patients also report mild to moderate symptoms of anxiety or depression.

What causes CFS?

CFS may occur after an infection such as a cold or viral syndrome, and it can start during or shortly after a period of high stress or come on gradually without any clear starting point or any obvious cause (Mayo Clinic Staff, 2014). Scientists have yet to identify what causes CFS (Centers for Disease Control and Prevention, 2012).

How is CFS treated?

A variety of therapeutic approaches have been described as benefiting patients with CFS, and because no cause for CFS has been identified and the cause remains unknown, treatment programs are directed at relief of symptoms (Centers for Disease Control and Prevention, 2012). There is no proven cure for CFS, although lifestyle modifications may make symptoms more manageable. The treatment of CFS focuses on symptom management. Some individuals with CFS benefit from a healthy diet; antidepressant, antianxiety, and sleep disorder drugs; and behavioral therapy.  In addition, relaxation and stress reduction techniques may be beneficial. CFS symptoms can change over time, and a combination of therapies that address symptoms, coping techniques, and managing normal daily activities may be helpful.

CFS and the Americans with Disabilities Act

Is CFS a disability under the ADA?

The ADA does not contain a list of medical conditions that constitute disabilities. Instead, the ADA has a general definition of disability that each person must meet (EEOC Regulations . . ., 2011). Therefore, some people with CFS will have a disability under the ADA and some will not.

A person has a disability if he/she has a physical or mental impairment that substantially limits one or more major life activities, a record of such an impairment, or is regarded as having an impairment (EEOC Regulations . . . , 2011). For more information about how to determine whether a person has a disability under the ADA, visit http://AskJAN.org/corner/vol05iss04.htm.

When requesting an accommodation, do employees with CFS have to tell their employers that they have CFS?

Under the ADA, when an employee requests an accommodation, an employer can require sufficient medical documentation to determine whether the employee has a disability and needs the requested accommodation. According to the Equal Employment Opportunity Commission (EEOC), sufficient medical documentation can include the name of the medical condition. The employee may want to begin by giving a more general description of the condition, such as saying “I have chronic fatigue syndrome,” and see if that suffices. However, such a limited description does not tell the employer that the individual has an impairment that substantially limits a major life activity because it is vague.

To increase the chance that the employer will settle for the use of a vague term, the employee may want to provide a letter from his/her doctor that confirms the existence of "chronic fatigue syndrome,” but then goes on to give concrete information about how the condition substantially limits a major life activity. The inclusion of concrete information may satisfy the employer. However, if the employer insists on knowing the diagnosis and the individual refuses to divulge it, the employer probably has a valid reason to refuse to provide the requested accommodation.

Accommodating Employees with CFS

Note: People with CFS may develop some of the limitations discussed below, but seldom develop all of them. Also, the degree of limitation will vary among individuals. Be aware that not all people with CFS will need accommodations to perform their jobs and many others may only need a few accommodations. The following is only a sample of the possibilities available. Numerous other accommodation solutions may exist.

Questions to Consider:

  1. What limitations is the employee with CFS experiencing?
  2. How do these limitations affect the employee and the employee’s job performance?
  3. What specific job tasks are problematic as a result of these limitations?
  4. What accommodations are available to reduce or eliminate these problems? Are all possible resources being used to determine possible accommodations?
  5. Has the employee with CFS been consulted regarding possible accommodations?
  6. Once accommodations are in place, would it be useful to meet with the employee with CFS to evaluate the effectiveness of the accommodations and to determine whether additional accommodations are needed?
  7. Do supervisory personnel and employees need training regarding CFS?

Situations and Solutions:

A customer service representative with CFS and memory and concentration problems had difficulty answering some customer questions. She was accommodated with written materials to help her remember information and a private office to reduce distractions.

A design engineer with CFS had difficulty working fulltime. He was allowed to work-at-home three days a week.

A student with CFS had difficulty keeping up with class notes. He was accommodated with a laptop computer to use in class.

An operating-room nurse with CFS had difficulty rotating schedules. She was accommodated with a permanent day schedule.

A teacher with CFS had difficulty meeting the physical demands of her job and was exhausted by early afternoon. She was provided with a teacher’s aid, her off-hour was moved to the afternoon, and she was excused from afternoon recess duty.

A daycare director with CFS had difficulty getting to work on time and maintaining a fulltime schedule.  She was allowed a later start time and a part-time schedule.

A flight attendant with CFS was missing a lot of work due to fatigue. Her doctor recommended that she reduce the amount of traveling she was doing. She wanted to continue working fulltime so requested reassignment to an office job.

A school psychologist with CFS was having difficulty working at full production. She was allowed to schedule appointments in the morning, which gave her uninterrupted time in the afternoon to complete paperwork. She was also allowed to schedule several short rest breaks throughout the day and use of sick leave as needed.

A social worker with CFS experienced headaches and photosensitivity. Accommodations included changing the lighting in her workstation from fluorescent lighting to task lighting, adding a glare guard to her computer monitor, providing window blinds, and implementing other workstation changes to enhance ergonomics.
