PHILADELPHIA — The owner of The Philadelphia Inquirer, its sister paper the Philadelphia Daily News and their joint website is seeking to eliminate 30 to 35 newsroom positions through buyouts.

The Philadelphia Media Network also announced Monday it’s hiring 10 people for new digital-related jobs.

Publisher Terrance Egger says “the economics are not getting any better” for the business.

He says the company needs to cut costs but is also investing to modernize its news operation and expand its audience on Philly.com.

The combined personnel moves represent about a 10 percent reduction in the 210-member union staff.

Union employees at the company since October 2010 are eligible for 28 week’ severance pay. They also can get lump sums of $2,500 to $15,000 based on seniority.
