GREEK workers see the longest job tenure in Europe. In 2005 they had spent an average of nearly 13 years with the same employer, according to the OECD's Economic Survey of the European Union. Within Europe workers changed jobs quickest in Britain and Ireland, where flexible labour laws make it easier to hire and fire and where growing economies mean workers are tempted by new opportunities. Employees are most mobile in America (or perhaps most-easily fired), putting in an average of just four years for one boss.
