Nearly 60 schools in 11 London boroughs are being targeted by trade union strikes next week (9-13 June) in a dispute over London Weighting.
Unison is targeting several secondary schools, putting GCSE and A-level exams under threat. The union is demanding a £4,000 London Weighting increase for all local government workers in the capital. Libraries, parking attendants, customer services and housing benefit services are also being targeted in some boroughs.
Councillor Ann John, chairwoman of Employers' Side of the Greater London Provincial Council, called the action unacceptable.
She said: "Councils and schools have gone to great lengths to ensure exams can go ahead without disruption. Unfortunately, the union action will mean that other children will miss out on important lessons and parents will be inconvenienced.
"These employees had an above inflation pay rise last year and an additional 3.5 to 4.5 per cent in April this year.”
John claimed that meeting the unions' demands would cost London £250m - equating to an additional £90 per household.
