An anesthesiologist filed an ADA claim against his practice group claiming he was not reasonably accommodated for his disabling illness since his request to work a lighter schedule (i.e., not taking night call or weekend shifts) was denied by the group. The United States District Court for the Northern District of New York found that the physician was disabled but that night call and weekend coverage were essential functions of his job and requiring others in his group to pick up additional call duty or work extra weekends was an undue hardship on the group and was not a reasonable accommodation required by the ADA.
