Yahoo is preparing to lay off between 600 and 700 workers in the latest shake-up triggered by the Internet company's lackluster growth.

Employees could be notified of the job cuts as early as Tuesday, according to a person familiar with Yahoo's plans. The person asked for anonymity because Yahoo hadn't made a formal announcement.

The planned cutbacks represent about 5 percent of Yahoo's work force of 14,100 employees. It will mark Yahoo Inc.'s fourth mass layoff in the past three years.

The last two housecleanings have come under the company's current CEO, Carol Bartz. She was hired nearly two years ago to engineer a turnaround that still hasn't happened.

This round of reductions is expected to be concentrated in Yahoo's U.S. products division.
