Bin workers at 15 Scottish councils including Inverclyde will go on strike in a new wave of industrial action later this month.
The Unite union said about 1,500 members would walk out from 24 August to 31 August over a pay dispute.
It follows a first wave of strikes in Edinburgh next week during the city’s International and Fringe festivals.
Unite said the action would hit all council waste services in response to a “pitiful” 2% local government pay offer.
The councils affected are Inverclyde, Aberdeen, Angus, Clackmannanshire, Dundee, East Ayrshire, East Lothian, East Renfrewshire, Edinburgh, Falkirk, Glasgow, Highland, South Ayrshire, South Lanarkshire and West Lothian.
It is part of a coordinated campaign by Unite, Unison and the GMB unions to persuade the Scottish government and local authority body Cosla to make an improved pay deal.
Unite is the only union involved in this phase of strikes.
Thousands of workers in schools, nurseries and waste and recycling centres voted last month to take industrial action.
Deputy First Minister John Swinney last week announced that the Scottish government would give councils an extra £140m to help give staff a bigger pay rise.
