I've long wondered why a largely-automated site like eBay needs to employ 15,000 people. Soon it might not. In September, research firm Wedge Partners said eBay needed to cut 10 percent of its workforce. Now an employee tipster tells us such "big deep cuts" may come as early as Monday. Our unverified source reports that "marketing and product" and " all of the horizontal support is at risk." If the axe doesn't drop Monday, it "will be done by earnings call on the fifteenth." What's gone wrong? eBay sellers don't like auctions as much as they used to, and as just another fixed-price online store eBay hasn't been able to compete.
