You are of course usually required to support your request for Reasonable Accommodation with a medical report and records. Sometimes this includes having a physician working for your employer review and evaluate your medical records. That’s to be understood and a regular part of the RA process and sometimes a physician . What is not a part of the process is your supervisor demanding to see your medical records. Your employer and any physician they hire has to keep your medical records in strict confidence and away from your managers. Supervisors only entitled to have information necessary to evaluate your workplace limitations and the feasibility of necessary accommodations. Don’t be cowed into giving them more than that.
