Glasgow City Council trade union members are to strike for two days later this month over an equal pay dispute.
The workers, overwhelmingly women, will strike on March 29 and 30 in calls for equal pay compensation payments. They will then strike again in April if there is no resolution.
UNISON is calling on its nearly 9,000 members and, with their sister trade union also joining the action, it could see over 12,000 workers out on strike.
