The largest teaching union has rejected the government’s pay deal.

NASUWT general secretary Patrick Roach described the proposed offer as ’derisory and unacceptable’.

Two other unions, NAHT and NEU, have voted to accept the pay deal which includes a one-off lump sum of £2,850 for senior leaders and £1,850 for those on the upper pay range.

Mr Roach said: ’Teachers in the Isle of Man have seen their pay fall by 30 per cent in real terms since 2010, significantly more than teachers elsewhere.

’The NASUWT urges the DESC to come back to the negotiating table with an improved offer which recognises the historic erosion and represents a fair and equitable settlement for teachers and lecturers.

’Teachers who have kept the island going during the coronavirus pandemic deserve better.

’The NASUWT stands ready to engage with the DESC at any time, but until a resolution is found NASUWT members will continue with industrial action short of strike action.’

The NASUWT has more than 300 teaching members who were eligible to vote.

Last month, members of school leaders’ union NAHT voted overwhelmingly in support of the deal. There were 121 eligible to vote and 81 did do, with 79 voting to accept the deal and just two voting against.

The NEU also voted for the deal. It has 542 members but these include retired teachers, support and supply staff and college lecturers. Of the 288 eligible to take part in the digital ballot, 175 voted of whom 56% voted for the pay offer and 44% against.

Ballot results from a fourth union, ASCL, are expected this week.

Under the proposed offer, the one-off lump sums to senior leaders and those on the upper pay scale will be funded by £1.5m of new money.

The deal also includes a commitment to review pay talks in any year in light of local conditions, discontinue appraisals, postpone external validations until August 2021 and to have union involvement in the Education Bill.
