A Scottish private school has become the first fee-paying secondary in Scotland to grant union recognition.
Hutchesons' Grammar - the alma mater of both First Minister Humza Yousaf and Scottish Labour leader Anas Sarwar - has now signed an agreement with three teaching bodies.
The move, described as "historic", now formally recognises trade unions for the purposes of collective bargaining over teachers’ terms and conditions.
It has been agreed between Hutchesons’ Educational Trust, NASUWT, the Educational Institute of Scotland and the Scottish Secondary Teachers' Association.
Dr Patrick Roach, NASUWT General Secretary, said: “This is a historic step forward in securing the rights of trade union members in the independent sector to be formally consulted over their working conditions.
“Through working together we can make schools healthier and safer places to work in for teachers and better places to learn in for pupils.”
The agreement follows a campaign of strike action by members of the NASUWT last year over attempts to downgrade the pensions of teachers at the school.
After teachers appeared on picket lines outside the school, in Glasgow's southside, action resulted in an agreement over pay and pensions.
A spokesperson for Hutchesons' Grammar said: “Over the past few months we, at Hutchesons’ Grammar School, through the Rector, Bursar and Director of People, have been working closely with the trade unions to develop a Recognition and Partnership Agreement (RPA) which establishes a framework for both parties to raise, negotiate and consult on relevant matters.
