The largest teachers' union in Jersey, the NASUWT has branded the States 'hostile' in its communication over the pay dispute.
Earlier this week, the States Employment Board hinted towards a 'breakthrough' in discussions, which is now being labelled as 'inaccurate and unacceptable' by the Union.
On Tuesday, National Education Unions members walked out on strike.
Jersey's Chief Minister John Le Fondré then said the NEU's stance to not partake in educational reforms and agree to pay rises through share savings, meant it was "deliberately harming our children’s education and causing cost and inconvenience to parents and employers."
The NASUWT made the decision to take industrial action short of strike action and asked members to refuse to cover lessons. This move has meant Le Rocquier School is closed to Year 9 today.
