HistoryThe service's roots lie in 1896 when the government set up a voluntary conciliation and arbitration service. There was a name change in 1960, to Industrial Relations Services, and again in 1972 to Conciliation and Advisory Service. Up to this point in its history the service remained firmly under the Government's wing.
The current ACAS, originally called the Conciliation and Arbitration Service, was set up with an independent council to direct it in 1974. "Advisory" was added to the name in 1975 to reflect the full range of services on offer. Finally, in 1976, the new organisation was put on a statutory footing and receives its funding through the Department of Trade and Industry. Its current chair as of October 2007 is Ed Sweeney.
