Beginning in 1986, Paul Rangel was a sales professional for the pharmaceutical company sanoaventis U.S. LLC (S-A). Rangel had satisfactory performance reviews until 2006, when S-A issued new "Expectations" guidelines that included sales call quotas and other standards that he failed to meet. After two years of negative performance reviews, Rangel-who was then more than forty years old-was terminated. The termination was part of a nationwide reduction in force of all sales professionals who had not met the "Expectations" guidelines, including younger workers. Did S-A engage in age discrimination?
