A Vietnam War veteran diagnosed with post-traumatic stress disorder was employed at the post office. After missing significant time at work for depression related to the PTSD, he requested an accommodation. The post office refused the request on the ground that his condition did not prevent him from engaging in any major life activity as required by the Rehabilitation Act. Has the post office violated the Rehabilitation Act? Is the post office correct in asserting that the depression does not prevent the employee from engaging in any major life activity?
