Union leaders have accused the Government of "fooling" hundreds of thousands of low-paid council workers out of a promised £250 pay rise.
Unison said carers, school dinner ladies, cleaners and teaching assistants in Wales, England and Northern Ireland would not be receiving the money in the new financial year.
The union pointed out that Chancellor George Osborne promised more than a year ago that public sector workers earning less than £21,000 would receive a £250 pay rise.
But local government workers have not received the money, Unison complained.
National officer Heather Wakefield said: "It is a disgrace that George Osborne has tried to fool local government workers and the public into believing he cared enough about the hardship of low pay to announce he would cushion the impact of the Government pay freeze.
"Hundreds of thousands of low-paid, mainly women workers - who every day care for people in our local communities - the carers, cleaners, cooks, teaching assistants and many more, have been fooled out of the £250 promised by George Osborne."
Council workers have suffered a 15% pay cut in three years and now earn a "shocking" 10% less in real terms than in 1996, said Unison.
