Members of the Writers Guild of America have ratified a successor three-year agreement with CBS News, covering about 325 employees.

The pact, which goes into effect Saturday, covers newswriters, writer-producers, graphic artists, editors, desk assistants, promotion writer/producers, assistant producers and production assistants in New York, Chicago and Los Angeles.

The new agreement, which will run through April 5, 2016, will increase wage scales by 2% annually and boost employer contributions to the Producer-Writers Guild of America Pension Plan. The WGA said it has also 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.

Deal was negotiated by the WGA East and the WGA West. Members working under the agreement ratified it by a vote of 159 to 31.
