Although somewhat outdated, the 2008 statistics from the California Department of Fair Employment and Housing indicate, as illustrated below that in the context of employment, disability claims represent a significant majority of all other discrimination complaints filed with the agency. This is not surprising in part because so many people sustain all kind of injuries at workplace and mostly industrial injuries and repetitive injuries (tendinitis, carpal tunnel, disc bulges). Many of such workers are retaliated against after they take disability leave or file a workers compensation claim. I worked with several managers who appeared to believe that because one of their employees was found to have exaggerated his injuries, all the others who request disability fake their condition. This is a dangerous generalization and mindset on the part of the employer which may result in significant liability in court, especially if the worker who claims disability discrimination is terminated.
Looking at the statistics below, I was surprised to see that age claims represent such a small minority of claims. I am pretty sure that one of the reasons that a relatively small number of age claims is filed is because they are so hard to prove. Unless there is a clear patter at a company of replacing older workers with the younger ones, or statements by the employer toward the victim that indicate age bias, such as encouraging an older worker to retire, calling him names such as "old time," "father," "old man" and making statements like "we need fresh blood in here" age discrimination is really hard to prove.
