Refuse loaders and drivers have backed strike action over their pay.
Loaders and HGV drivers currently earn one of the lowest wages for comparable services in the area.
For loaders this is usually £10.90ph and HGV drivers are on £11.89ph.
Michael Hall, GMB regional organiser, said:
"In a cost of living crisis every worker deserves decent pay. These refuse workers are asking simply for a fair pay offer.
"They do vital work for the community across Workington. This should be recognised with a wage that covers rising bills.
"This is why they've been left with no choice but to strike."
