No word yet on numbers, but it apparently came down a few hours ago. From the Business Insider:
Newsweek employees have been bracing for the staff cuts since early August, when it was announced that former stereo equipment mogul Sidney Harman would be the magazine's new owner. (His purchase of the magazine is just about finalized.) Harman had said from the outset that he planned to keep a "majority" of the staff on board. One estimate suggested he would trim the staff from a little more than 300 to about 250.
All this comes after this week's resignation of Howard Fineman, who has moved over to the Huffington Post.
