The Writers Guild of America East has unionized about 100 employees of Lion Television including writers, producers, associate producers and researchers.

The WGA East announced Friday that Lion had agreed to recognize the guild as the bargaining agent for the employees in the wake of the National Labor Relations Board certifying the results of an NLRB-supervised election in which employees voted for WGA representation.

Employees included those working on ”Cash Cab” for Discovery Network, ”Megadrive” for MTV, and ”History Detectives” and ”America Revealed” for PBS. Lion TV employees voted for guild representation in December as part of the guild’s organizing campaign at non-fiction basic cable production companies.

”We welcome the Lion employees into our creative community, where they will join thousands of other members who do some of the best work in television, film, radio, and digital,” said WGA East exec director Lowell Peterson. ”We are pleased that Lion respects their decision to become part of the Writers Guild and we look forward to a long and productive relationship.”
