On May 15, 2013, the EEOC issued revised "Q & A" documents addressing how the ADA applies to job applicants and employees with cancer, diabetes, epilepsy and learning disabilities.  http://www.eeoc.gov/eeoc/newsroom/release/5-15-13.cfm

Each of the revised Q & A documents also answers questions about topics such as: when an employer may obtain medical information from applicants and employees; what types of reasonable accommodations individuals with these particular disabilities might need; how an employer should handle safety concerns; and what an employer should do to prevent and correct disability-based harassment.  Notably, the Q & A documents state that even applicants and employees with diabetes and epilepsy may be qualified to operate Commercial Motor Vehicles requiring individuals to meet certain minimum physical standards under the U.S. Department of Transportation (DOT) regulations based on established DOT waiver programs. http://www.fmcsa.dot.gov/rules-regulations/administration/fmcsr/fmcsrruletext.aspx?reg=391.41.  Thus, the revised guidance may be of particular interest to employers in the trucking industry.
