Talks between unions and Aberdeen City Council over the implementation of equal pay rules have collapsed.
The issue took the council to the brink of industrial action last month, which was averted when the council withdrew letters sent to about 2,000 workers warning that they faced pay cuts of between £1,000 and £20,000 under the new legislation.
The Transport & General Workers’ Union said it was not being given information to which it was entitled.
Union official Tommy Campbell said: “Our shop stewards met last Wednesday and had a full report from our convenors, following which it was decided to register a formal dispute with the employer by way of a failure to agree notice.
“We insist that the employer supply all the information it has, in line with terms of national and local agreement. The ball is now in the council’s court.”
