The general secretary of PCS, Mark Serwotka reiterated demands for justice for the Grenfell families, as the union marks the disaster three years ago today.
Two members of the union were caught up in the blaze and escaped the disaster with one mother tragically losing her child.
The union has campaigned alongside Grenfell solidarity groups and has supported several resolutions to the TUC including from the FBU last year.
Yet despite extraordinary efforts by campaigners and unions, there has been no prosecutions for those responsible for the plastic cladding which still remains on 1400 tower blocks to this day in Britain.
Mark Serwotka said: "Today we remember all those who lost their lives and send our solidarity to all of the families who have suffered. This entirely preventable disaster and the pain of so many families has been compounded by the lack of justice where incredibly no one has been prosecuted for what happened.
"There has been no ban on combustible cladding on residences around the country and in fact, around 1400 tower blocks are still wrapped in the same kind of materials that were present at Grenfell.
"Our union along with other organisations will never cease in our commitment to see justice prevail, for the families and the communities up and down the country that are still at risk of a Grenfell-style disaster."
