NEW YORK (CNNMoney.com) -- The job toll continued Tuesday, as Sony Corp. and five other companies announced cuts totaling nearly 15,000 positions.

Sony, Danaher Corp., Wyndham Worldwide, the National Football League and Principal Financial Group announced job cuts totaling about 14,400 positions.

In addition, Novellus Systems said it was cutting 10% of its global work force without specifying a number of employees, but the company had a headcount of 3,678 staffers on Dec. 12, 2007.

Sony (SNE), based in Tokyo, on Tuesday announced the most sweeping job-cutting plan of the three companies. Sony said it planned to "reduce headcount" in its electronics business by 8,000 jobs by March 30, 2010. The cuts will be implemented worldwide, the company said, from a total workforce of 160,000, according to a Sept. 30 headcount.

Sony, which produces a wide variety of consumer electronics, blamed "the acute downturn in the economic climate" for the job cuts. The company also said it was reducing its seasonal and temporary staff.

"These are difficult and painful steps, but they are necessary in the current economic environment," said Commissioner Roger Goodell in a memo to his staff, which was provided to CNNMoney.com.

He said the NFL would "emerge strong, more efficient" as a result of cuts.

Principal Financial Group (PFG, Fortune 500) said it is eliminating about 550 positions. This includes 300 jobs at its Des Moines, Iowa, headquarters and 250 jobs in 45 other locations, the company, equating 3.5% of its total workforce.

"Since September, when market conditions worsened, we have been continuously reviewing expenses and expected revenues," said Mary O'Keefe, senior vice president of Principal Financial, in a prepared statement. "In order to bring expenses more in line with projected revenues, we have already cut many expenses. Unfortunately, this must include eliminating some jobs."

Job cuts have been mounting all year. According to the Labor Department, the U.S. economy hemorrhaged 533,000 jobs in November, the largest monthly loss in 34 years. Through November, the economy lost of total of 1.9 million jobs, the government said, raising the unemployment rate to 6.7%.
