Voice and data networking provider 3Com ( COMS) will cut 10% of its workforce worldwide in the next two quarters, citing weak demand and the need to trim costs. In the U.S., employees at the company's headquarters in Santa Clara, Calif., office will be the most affected. Other workers in the U.S. and in Europe, the Middle East and Africa will also be impacted. At the end of February, 3Com had about 3,900 workers. "With the sale of our CommWorks unit, the company will function as a single operating entity, enabling a more competitive cost structure," said Bruce Claflin, 3Com's chief executive. "In addition, continued weakness in demand requires we improve the company's overall cost structure, particularly in G&A related activities." 3Com will increase its sales, marketing and customer service capabilities to compensate for weak demand. The company said it will speed up these efforts as the 3Com-Huawei partnership announced on March 19 becomes operational. The company also said it will continue to do "selective hiring for key skills and in areas that directly contribute to our enterprise strategy, such as adding field resources in order to help our distribution partners drive sales." Shares of the company were up 2 cents to $4.98 in recent Nasdaq trading.
