GlaxoSmithKline notified the state Monday that it plans to eliminate 180 jobs at its Durham offices effective June 1.

On Friday, The Philadelphia Business Journal reported that the company would cut about 150 positions there.

GSK spokesperson Melinda Stubbee told the newspaper:

“These are not new job reductions, but are the continuing implementation of the reductions we announced in early December 2014.”

That downsizing will see a total of about 900 jobs eliminated – about 20 percent of GSK’s nearly 4,500 work force in RTP.  GSK employs about 17,000 people in the United States.
