WORKMEN fitting out council homes in Deighton claim they face verbal abuse and physical threats on a daily basis.
And in one chilling incident two months ago, a workman was treated in hospital after a violent attack.
Teams of builders, plumbers and electricians are working on bringing all the homes in the area up to the Decent Homes Standard.
The Government states that all council houses should be of a certain standard by next winter, with modern facilities, good insulation, efficient heating and proper waterproofing.
The scheme to renovate 18,000 Kirklees council homes, started in May, 2003, and is well under way. The work is being carried out by a contractor employed by Kirklees Neighbourhood Housing.
One contractor, who wished to remain anonymous, said the situation was desperate.
He added: "People are getting grief all the time.
"The vast majority of the community are very helpful and are appreciative of what we do, but there is a small element who seem intent on causing trouble.
"Workmen are facing tirades of abuse on a daily basis. Threats of violence from some residents are common.
"It can be an unpleasant place to work."
The contractor said he had been subjected to threats, abuse and thefts while working on the estate.
He added: "Some attacks have been reported to the police. It is just day on day.
"Some builders have walked out of homes - whether it's the state they are in or abuse they face.
"They just turn the other cheek and can't say anything."
The contractor said his wife had implored him not to go back to work.
He added: "When she hears what happens she asked me not to go back.
"She fears for my safety. The area never used to be like this.
"It is a shame that a small minority want to carry on like this with people who just want to get on with their jobs and make these houses nicer."
A spokesman for KNH said they would not tolerate their staff being intimidated or abused by anyone.
He added: "We enjoy excellent relationships with the vast majority of our tenants, who are only too pleased with the improvements being made to their homes.
"However, there have been isolated incidents involving a few individuals when staff have been harassed or assaulted. In these cases, we have involved the police, completed incident reports, and stopped work on tenants' homes."
The spokesman said they held regular health and safety meetings with all staff, contractors and tenants.
He added: "We would urge anyone with concerns about their safety to let their manager know immediately."
