NASUWT national officers and senior activists went to Brussels to take part in a mass demonstration calling for “A fairer Europe for workers”.
They joined around 8,000 trade unionists at the rally organised by the European Trade Union Confederation in April.
Senior Vice-President Michelle Codrington-Rogers and National Treasurer Russ Walters attended the protest.
National Executive Members Simon Ackerley, Harold Gurden and Nigel Williams also took part.
Michelle Codrington-Rogers said: “NASUWT is part of the European rally for a fairer Europe because it’s about standing in solidarity with colleagues across Europe.
“It’s also a big message to say that we are part of a wider trade union movement, across Europe especially, and an attack on one is an attack on all.”
The demonstrators were representing member organisations of the European Trade Union Committee for Education (ETUCE), the European arm of Education International.
They came from many countries, including the UK, Belgium, France, Germany, Italy, Spain, Switzerland, Austria, Hungary, Slovenia and Estonia.
After gathering outside the European Parliament, the protestors marched through the streets of Brussels together.
Their aim was to draw attention to the forthcoming European elections and raise awareness of the ETUCE’s campaign, Shape the Future of Europe With Teachers.
The march finished with a rally near the European Council and Commission where a number of speakers addressed the crowd.
Russ Walters said: “We want a stronger Europe, a stronger Europe that can stand up for democracy, stand up for the real values of life and oppose the radical right wing, which seems to be creeping in throughout our countries.
“So it’s great to be amongst our colleagues where we can show this feeling in depth.”
