The Americans with Disabilities Act (“ADA”) may require employers to allow disabled employees well more than six months of unpaid leave as a reasonable accommodation, according to a federal district court in western Washington. There is no doubt that unpaid leave beyond the three months guaranteed by the Family and Medical Leave Act (“FMLA”) can be a reasonable accommodation under the ADA. But the district court’s October 23 decision in Casteel v. Charter Commc’ns. Inc. suggests that such a reasonable accommodation might include unpaid leave of surprising length.
