Fair Pay launched in November 2007 as the official website of the Fair Pay Action Group. It was a response to the pay cuts brought in by a Labour Council in the name of the Single Status Agreement. The Single Status Agreement was finalised by the unions in 1997 and was designed to implement the 1970 Equal Pay Act in 2007, and also work as a defensive measure against expensive tribunals brought against councils in the name of the Act. This site, and the group's members, worked to oppose the cuts, publicise the workers' plight and lobby councillors and politicians.
Today Fair Pay is fully independent and no longer associated to a particular council, nor is it part of the Fair Pay Action Group.
