USi is an initiative of major UK and Irish trade unions, and is supported by unions in Brazil, Greece, Austria, North America, Europe, South Africa and Australia that aims to build grassroots international union solidarity using the latest technology. We link trade union activists from around the world directly with each other so that you can create and lead campaigns for a fairer and more sustainable world.

If you’re doing something exciting and relevant to build union solidarity, we’d love to help spread the word.

We use social media, blogs, video conferencing, online education and more to build networks and provide you with fresh content in the global fight against austerity.

Get involved! Write for us, share stories and campaigns with us, sign up for updates, or join one of our regular web conferences.
