In addition to a 7.9% pay rise for 2023, teachers had been offered an 8% increase from 1 January 2024, a one-off payment of £1,000 on the same date and pay rises matching inflation for 2025 and 2026.

The strikes will take place on 12, 13 and 14 December.
Caryn Symons, NEU Senior Regional Officer, said: “The current offer simply does not address the real terms pay cut and the issues being experienced in Jersey by the escalating costs of living.
“Our members continue to struggle with their bills and supporting their families. Increases in mortgage rates are adding large sums to monthly outgoings, rent is challenging and debt is continuing to rise for our members. These are real issues for our members and need to be addressed promptly.
“It is disappointing that we remain in the position where our teachers are left with no alternative but to show their disapproval of the offer by withdrawing their labour next week.”

The NEU has already staged strikes earlier in the autumn term, although the most recent action at the start of November was postponed as a gesture of goodwill after schools were forced to close for at least two days because of Storm Ciarán.
The other main teachers union, the NASUWT, is also consulting members on the Government’s offer, with the ballot set to run until 15 December.
On Monday the NASUWT confirmed it would suspend the work-to-rule industrial action, started on 27 November, while the ballot was taking place. The action had caused a disruption to normal operation in many schools, with pre-school clubs and other extra-curricular activities being affected.
