Lincolnshire’s parking warden service has seen 100 per cent staff turnover in six months.
Stress and sickness has been blamed for wardens leaving their jobs.
Motorists have physically attacked and threatened the 20-strong team of wardens on virtually a daily basis since Lincolnshire County Council took over responsibility for enforcing on-street parking from police.
Every warden has been given a body camera and GPS tracking device to record the attacks.
Mick Phoenix, parking services manager at Lincolnshire County Council, said: “100 per cent of the team that started on December 3 has been replaced at least once.
"It is down to stress of the job and sickness.
“They receive abuse from motorists. And even in the least serious cases, let's just say they are subject to the odd quiet word from drivers."
There have been 35 recorded cases of wardens being threatened since they started work on December 3.
But Matt Jones, parking services officer at the county council, said the number "does not reflect the true extent of the problem, as wardens often face abuse on a daily basis".
Michael Brookes, chairman of the highways and transport scrutiny committee at Lincolnshire County Council, said: "These wardens simply cannot cope.
"It is a massive concern. A 100 per cent staff turnover is as bad as it gets in such a short space of time.
"We need to work very closely with the contractors to make sure the new wardens we are bringing into work on our streets in Lincolnshire are up to the job.
"It must be an extremely difficult job and only a certain person could do it."
Andrew Fitzsimons, spokesperson for APCOA, the contractors for the county's civil parking enforcement scheme, said the body cameras film the wardens' entire shift and any evidence of them being attacked is passed onto police.
“The bodycams and tracking devices provide us with valuable support to ensure we are at close hand at all times to support our team," he said.
"We always report all abuse to the police."
Overall, 22,675 tickets were issued between December 3 and June 30.
Keith Smy, assistant chief constable at Lincolnshire Police, said: "I am concerned to hear the new wardens have suffered verbal and physical abuse at the hands of the motorists they are dealing with.
"I would encourage them to call us to report such incidents.
"It may be that some motorists took advantage of the fact that there was a transition period before the handover was made and took effect.
"Perhaps they became used to ignoring parking regulations and they now take exception to the intervention by the new wardens."
