Refuse collectors in Barrow are being asked if they want to take strike action.
Around 20 workers at FFC Environment, members of the GMB union, are taking part in the ballot over pay.
Staff are asking for a three per cent pay increase.
The GMB began balloting members today and it will close on February 7.
If the strike goes ahead, more than 33,000 households in Barrow could be affected, the GMB said.
Michael Hall, GMB organiser, said: “Despite inflation running above seven per cent, all Barrow’s refuse collectors are asking for is a three per cent pay rise, so they can keep their heads above water.
“The last thing they want to do is inconvenience the people of Barrow by not emptying their bins, but FCC have backed them into a corner.
“GMB urges management to negotiate and properly value what these keyworkers do, before they are left with no choice but to go out on strike.”
