It looks like HP could be in store for another wave of big changes. According to a pair of reports out today (backing up a report from Business Insider yesterday), HP CEO Meg Whitman will announce a new restructuring plan on the company's earnings call next Wednesday -- a plan that will entail some significant job cuts. Bloomberg pegs those cuts in the neighborhood of 25,000, while All Things D says they could include as many as 30,000 jobs, noting also that the number is still a "moving target." To put that in perspective, the company currently employs some 320,000 people worldwide. Of those cuts, 10 to 15,000 are said to come from HP's enterprise services group, and the company is also said to be offering early retirement packages to some 5,000 employees. That restructuring plan will apparently include more than just job cuts, though, with Whitman said to be pushing a "cut and reinvest" approach that will apply across the company, according to ATD.
