The Writers Guild of America has reached a tentative agreement with CBS News for a three-year successor deal to its current three-year contract.

The deal covers about 325 news writers, producers, editors, graphic artists, production assistants and promotion writers working in the network’s TV and radio news operations in New York, Los Angeles, Chicago and Washington, D.C. If ratified by members working under the current pact, the new agreement will replace that deal, which had been due to expire Tuesday.

Negotiations were handled by representatives from the WGA East, which has about 200 members covered, and the WGA West. No details of the terms of the tentative agreement were disclosed.

Members ratified the current agreement in 2013 by a 159-31 vote. That deal increased wage scales by 2% annually and boosted employer contributions to the Producer-Writers Guild of America Pension Plan.

The WGA also said in 2013 that it had achieved gains in contract producer minimum salaries and acting editor fees. “There are no concessions on the part of the union in the agreement,” the guild added.
