The company that helps people find jobs is itself cutting back on workers. Internet job board Monster Worldwide ( MWW)laid off 400 jobs on Jan. 25, or 7% of its global workforce, in an attempt to improve revenue generation. Less than 100 of the cuts are in Massachusetts, where the company's headquarters are located. Monster said in a press release that it would increase sales and marketing going forward. In 2010, the company completed the acquisition of Yahoo! HotJobs, a $225 million deal that gives Monster exclusive ability to provide job content for Yahoo!'s U.S. and Canadian homepages.
