The Writers Guild of America, West is ordering writers who work on some Comedy Central shows to put down their pens.
In a letter send to members Monday, guild leaders told members to not work on any Comedy Central shows without first checking with the union to ensure the writing is "guild-covered."
The union said the action came about after the guild learned that Central Productions -- the production arm for Comedy Central -- hired writers on more than two dozen new projects earlier this year without first securing deals with the guild.
The WGA did not say which shows were affected by the stop work notice, but said it has been negotiating with Central Productions to secure contracts for those shows.
"No other major entertainment company has treated writers and their Guild so cavalierly," the letter stated. "It is never easy to ask a fellow member to stop working. We understand all too well that such a call comes with the real possibility of personal sacrifice. We do not do it lightly. But the principle that we work, all of us, under a contract with certain basic protections that may not be undercut and that may not be re-negotiated, member-by-member and case-by-case, is the cornerstone of our strength."
