Talks are being held to avert a strike by 600 council refuse collectors and street cleaners in Leeds after negotiations over pay ground to a halt.
Officials from the GMB union are meeting managers at Leeds City Council in a bid to break the deadlocked dispute and avoid workers going on strike.
GMB official Bill Chard said: “GMB obviously regret the inevitable disruption that this strike action will cause to the people of Leeds.
“Not only will the bins not be emptied for weeks and weeks on end but if people live near a fish and chip shop or any of the fast food takeaways then the bins outside those premises will overflow on to the streets too.”
The threat of a strike in Leeds is one of many disputes among public sector workers over pay, jobs and services.
Services in Liverpool are due to be disrupted later this week when 600 council workers stage a series of walk outs after a breakdown of pay talks.
