Four unions representing tens of thousands of youth and community workers in the voluntary sector have said they will demand a substantial pay rise.
According to Unite, Unison, college union the UCU and the National Union of Teachers, the youth and community sector has a shortage of about 4,000 workers, and it will be filled only if there is a large pay rise for all employees.
The unions are also calling for voluntary sector projects to be given longer-term funding arrangements in order to improve job security for workers.
The unions will meet voluntary sector and local authority employers to discuss the potential pay rises on 15 June.
Doug Nicholls, national secretary for community and youth workers at Unite, said the claim was "the most important pay submission for a generation" in youth services.
