two biggest teaching unions have voted to strike over London allowances.
National Union of Teachers and the NASUWT teaching union said they will stage a
one-day strike on 26 November.
third main classroom teaching union, the Association of Teachers and Lecturers,
is due to ballot on industrial action over the same issue.
three unions want the London allowance doubled, from just over £3,000 to £6,000
– the same rate paid to police officers.
