Leeds City Council has described the proposed action as "regrettable"
Refuse collectors in Leeds are taking continuous strike action in an ongoing pay dispute with the council.
The GMB and Unison unions said the starting date for the strike would be decided on Friday.
They are unhappy with the council's proposals to slash their pay by up to £5,000 per year from February 2011.
Union leaders are planning to meet council officials in the city on Thursday to try to find a resolution to the dispute.
In a statement, the GMB, said: "The employees feel that they have no choice but to take continuous strike action with no fixed end date in an attempt to stave off the massive pay cuts that Leeds City Council wish to impose on them."
Last week refuse collectors voted by more than two to one in favour of industrial action.
In a statement issued at the time, Leeds City Council said industrial action was "regrettable".
"We are disappointed Unison and the GMB have chosen this course of action", it said.
The statement added: "We have contingency plans in place, and will do our best to keep any disruption to services to a minimum where possible."
