Harold recently applied for a transfer within his company to a new position. He has a physical disability that requires him to utilize a walker to get from place to place. Harold’s current position is in payroll and he easily completes this task from the comfort of his desk. The new job opening requires administrative and supervision duties with certification in OSHA training. Harold does not have the OSHA certification, but two other non-disabled applicants do. When he does not get the position, Harold considers filing a claim with the Americans with Disabilities Act. Does Harold have a valid claim?
