IT giant IBM told Personnel Today that the firm's global workforce of 399,000 permanent employees could reduce to 100,000 by 2017, the date by which the firm is due to complete its HR transformation programme. Tim Ringo, head of IBM Human Capital Management, the consultancy arm of the IT conglomerate, said the firm would re-hire the workers as contractors for specific projects as and when necessary, a concept dubbed 'crowd sourcing'. "There would be no buildings costs, no pensions and no healthcare costs, making huge savings," he said.
