The WGA East today accused NBCUniversal of “union busting” in a dispute over the shuttering of its now-defunct Peacock Productions, formerly the in-house nonfiction production wing of NBC News. The guild, which had a contract with Peacock, says that many of the unit’s former writer-producers have been reassigned to the newly created NBC News Studios, which doesn’t have a contract with the guild.

The guild, which filed an unfair labor practices (ULP) complaint last month with the National Labor Relations Board, filed another one today.

“NBC News is continuing the work of Peacock Productions under a different banner, using Peacock Productions employees,” the guild claims. “There is one key difference: the company is refusing to apply the WGAE collective bargaining agreement to any of those employees.”
