Members of the Transport and General Workers Union at Moray Council have accepted proposals on equal pay.
The talks could settle a long running equal pay dispute
However union officials made clear on Friday that they had "reluctantly decided to accept management proposals" for council employees.
Two out of the three unions - Unison and the GMB - had already accepted the £5.6m Single Status agreement.
Tommy Campbell from the TGWU says his members were accepting Moray Council's pay package under protest.
