Union leaders have warned they will pursue tribunals for hundreds of members at Aberdeen City Council if a row over pay is not resolved.
Legal and industrial action was earlier threatened over the plan to scrap a 1% annual rise in pay for workers to help make savings.
A new offer in a bid to settle the dispute will go before the full council next week.
GMB Scotland warned demands would have to be met to avoid action.
The council is trying to make about £120m of savings over the next five years.
Janet Adams, GMB Scotland's regional organiser for Aberdeen City Council, said: "Until we reach a satisfactory conclusion we will continue to actively pursue these claims at the tribunal."
