Adecco, the world’s biggest temporary staffing company, expects demand to improve as employers seek flexible labour to fill jobs in an uncertain recovery. This year got off to a good start, with sales rising 17 per cent organically in January from a year earlier, chief executive Patrick De Maeseneire said yesterday. Temporary employment is seen as a leading indicator for wider labour markets. So far, many employers have been reluctant to commit to full-time hiring, preferring temporary workers as a way of staying flexible in case the recovery falters. “The environment will stay favourable for flexible labour”, Adecco said. It said that unemployment would remain high in developed economies.
