Fox leaves the NAS pack baying
Ms Fox, aged 39 and from a social work background, was an unusual appointment as Scottish regional official of the National Association of Schoolmasters Union of Women Teachers. She had been London regional officer with the public sector union Unison for three years before moving back to Scotland.
Ms Fox has been off work since June. She confirmed her resignation to The TES Scotland and said she intends to take a law degree at Strathclyde University. Pa O'Donnell, a former NAS president in Scotland who teaches at St Vincent's primary in East Kilbride, will take over until December.
Ms Fox had continuing battles with a number of senior figures in the union, some of whom had been contenders for her job. This culminated in a year's suspension handed out to Jack Duffy, Glasgow secretary and national salaries convener, for bringing the union into disrepute following a run-in.
She stood for Labour in Edinburgh West at the Holyrood elections and is expected to spend more time on her political career.
