Union treasure trove marks 75 years of Ucac’s work
Monday 14th December 2015
A WELSH trade union is marking its 75th anniversary today by opening an online treasure trove of retro memorabilia.
Protest photos, historical documents and radical posters are among items on the digital archive of teaching union Undeb Cenedlaethol Athrawon Cymru (Ucac).
Members past and present as well as descendants of the union’s founder members have been searching their attics to unearth the treasures.
General secretary Elaine Edwards pointed out: “To this day, Ucac is the only trade union established in Wales specifically for workers in Wales.
“We’re extremely proud of our historical roots and stick steadfastly by the vision and guiding principles of Ucac’s founding members. Ucac is, and always will be, a union that puts Wales’s teachers and lecturers first.”
