Plenty has been said already about IBM\u2019s shift in how it reports its employee headcount. In its most recent annual report, which you can see\u00a0here, IBM provides only a global headcount of 399,409 employees instead of providing in specifics on the number of employees it has in the U.S. For the most part, the talk has been critical. That\u2019s not surprising. Most people don\u2019t like it when companies keep secrets, even those secrets they are legally able to keep. For its part, IBM reportedly has said it\u2019s only doing what most of its competitors already do.For a great breakdown of IBM\u2019s change of heart, read this story by Computerworld\u2019s Patrick Thibodeau.What I found particularly interesting is the commentary from Ron Hira, an associate professor of public policy at the Rochester Institute of Technology. Hira charges that IBM is hiding its offshoring, and in doing so is hiding workforce data that policymakers need to better understand how offshoring affects the U.S. market.Moreover, Hira points out, IBM\u2019s less-than-full disclosure seems to be in keeping with its opposition to President Barack Obama\u2019s proposal to change the tax deferral rules, which could outlaw or restrict billions in tax breaks U.S. companies who offshore. (IBM isn\u2019t the only company opposing these changes; others include Microsoft and Symantec.)IBM\u2019s shift to providing only global employee counts comes in an annual report that\u2019s written about a year in which IBM apparently dropped some 10,000 U.S. workers. The annual report doesn\u2019t necessarily reflect that number, however. The 10K layoff number is an estimate from the Alliance@IBM\/CWA Local 1701, a worker union bargaining for employee rights. The annual report states that IBM finished up with more employees by 0.2%, or just short of 1,000, from 2008. Hmmm\u2026I get that IBM doesn\u2019t legally have to break out its employee headcounts by region for you, or me, or shareholders, or anyone. But it has in the past. The shift seems a little odd at best. Really, why be so tightlipped IBM? It\u2019s a simple HR task to break out the U.S. numbers. My guess is you\u2019d rather the American public not know how many U.S. jobs may have been lost to offshoring.What do you think, readers? Is this business as usual, a shady move, or perfectly legit?
