The New York Times Company announced that it plans to lay-off 500 workers in coming months—that’s 4 percent of its workforce. The announcement came just hours after the Philadelphia Inquirer and the Philadelphia Daily News announced a planned buyout of 15 percent of its newsroom staff. The New York Times newspaper will cut 250 jobs, including 45 newsroom employees. The company’s New England Media Group, which includes the Boston Globe, will lose about 160 jobs, including 35 in the Globe newsroom. The rest of the cuts will be made in other parts of the company, including its smaller regional papers and radio and television stations.
