IBM ( IBM) revealed in a filing today that 15,600 workers were involved in job cuts that were announced in early June. According to the company's 10-Q report, 14,213 of the workers were in the company's Global Services business. Most left the company by the end of June. The rest will go by the end of next month. Another 1,400 workers also were laid off, with the majority of that group leaving by the end of August. All those who were laid off were notified by June 30, according to the filing. The cuts, totaling about 4.9% of IBM's worldwide workforce, were widely anticipated and came at about the same time the company unloaded its hard-disk-drive division to Hitachi. Although revenue topped analysts' estimates for the June quarter , the company also reported a huge miss of estimated service contracts.
