A household waste collector has called for the protection of gardaí in some parts of the capital.
Greyhound Household says its collection crews are coming under attack by residents in some areas of the city.
A man was recently sentenced to two years in jail for assaulting Greyhound collection staff.
The company has released video footage of other incidents - where they say staff suffered threats, intimidation and assault.
In a number of cases, Greyhound say residents impeded the collection truck so they could tip large amounts of black bins into the green bin vehicle.
Greyhound's managing director, John Brosnan, said: "Our crews are experiencing an increase in threatening behaviour.
"We have a duty of care to the health and safety of our employees.
"We have reported the incidents to gardaí and also hope for assistance from local representatives.
"However, we may be forced to consider suspending collections on some roads. We are calling on people to respect our crews while they do a difficult job".
