Unite said around 1,500 of its members will be involved in the second wave of council strike action.
Workers will begin striking on 24 August until 31 August, in a move that will affect all waste services in the 15 councils.
Wendy Dunsmore, Unite regional officer, said: 'The failure of both COSLA and the Scottish Government to work to bring an improved offer to the table that could have halted this action means any blame for where we are now should be directed back to them. Unite will not tolerate that local government workers are the consistent poor relations and members have now had enough.
'We are calling once again on COSLA to make a fair and decent offer to workers now in order to avoid the forthcoming wave of strikes.'
