A teaching union has branded the decision to accept a new pay deal for teachers as "deeply disappointing".

A two-year deal on pay and conditions was formally agreed on Monday by the Scottish Negotiating Committee for Teachers (SNCT), which includes representatives of teaching organisations, councils and the Scottish Government.

The settlement will see teachers receive a 1.5% backdated increase for the financial year 2015/16 and a further 1% in 2016/17.

The National Association of Schoolmasters Union of Women Teachers (NASUWT) rejected it but was defeated by a majority vote to accept the offer.

Scotland's largest teaching union, the EIS, sought approval from its members before backing the deal.

The NASUWT said a canvass of its members showed there was overwhelming support for rejection.

General secretary Chris Keates said: "The NASUWT does not believe it is in the interests of teachers or the children and young people they teach to accept this offer.

"It is deeply disappointing that other members of the SNCT have accepted it.

"Teachers are thousands of pounds worse off as a result of the year-on-year cuts to their salaries. In addition, they have faced paying increased pension contributions and deteriorating working conditions.

"The award fails to address the full restoration of supply teachers' pay and conditions, which is a key reason for NASUWT's opposition to the award."

The EIS said the deal was the best that could be achieved through negotiation in a "difficult financial context".

Education Secretary Angela Constance said on Monday: ''Reaching this agreement on a pay increase demonstrates the benefit of government, employers and unions working together positively, particularly in the current challenging financial climate.''
