A former employee of Standard & Poor’s has filed a $5 million discrimination lawsuit that accuses the financial information company of allowing other employees to harass and humiliate him because of his Hispanic ancestry and then fire him because he complained. Raphael Garcia...says in papers filed in Manhattan’s state Supreme Court that somebody spat on his computer keyboard while he was away from his desk...[he] was called “dumb” along with vulgar names for people of Hispanic background, was paid less than white co-workers...A spokesman for the McGraw-Hill Cos., parent of S&P, said Garcia’s complaints were thoroughly investigated and were found to be unsubstantiated and without merit.
