According to Reuters, Merck & Co. plans to cut another 12,000 to 13,000 jobs by late 2015 to wring out additional annual cost savings of up to $1.5 billion that can be plowed back into research and deal making. The No. 2 U.S. drugmaker eliminated 12,465 positions last year, offset by almost 6,500 new hires, reducing its workforce to 91,000 employees as of June 30. The company, which also reported quarterly earnings in line with forecasts, said on Friday it would cut its workforce by an additional 12 percent to 13 percent from the 100,000 employees it had at the end of 2009 after buying Schering-Plough Corp. Job cuts will come largely from administrative positions, consolidation of offices and sale or closure of manufacturing sites. Merck is streamlining operations following its $41 billion purchase of Schering-Plough.
