From the New York Times: "The Writers Guild of America West said Thursday that it had filed an unfair labor practice complaint with the National Labor Relations Board against Tyler Perry's production studio after it fired four writers for the popular TBS situation comedy, House of Payne who were seeking union representation. Jeff Hermanson, an assistant executive director for the Writers Guild, said that the four writers, who were based in Los Angeles, were fired earlier this week after negotiations between the Writers Guild and representatives of Mr. Perry's production company, which is based in Atlanta, broke down."

Unfortunately, this is not uncommon. South Park is one show that does not employ WGA writers.
