James Whitlock worked for Mac-Gray, Inc. After he was diagnosed with attention deficit hyperactivity disorder (ADHD), he was allowed to build partitions around his workspace and use a radio to block background noise. Whitlock performed his work and taught himself to use Mac-Gray’s new computer system. He worked for a while but frequently called in sick and finally stopped working after his doctor said he was totally disabled. Whitlock, alleging he was disabled from working, sued Mac-Gray for workplace discrimination and violation of the ADA. Should he recover?
