IT job cuts in local government will continue for the next two years, says Socitm.
The reductions in IT staffing will increase pressure on local government IT departments to deliver more from less.
According to the latest IT Trends survey from Socitm, there was a 10% cut in IT staff at local authorities in 2009.
This will cause service levels to fall, says the report's author John Searle.
He said spending on IT will fall by 11% this year.
"There has never been a reduction in IT spending in the 23 years of this survey. It has had a detrimental effect on services and we cannot see the current business model working," added Serle.
He said demand for IT services is increasing and investment is decreasing.
However, one of the most effective ways to reduce costs is through IT investment. Self services, where online services support citizens, is an example.
John Suffolk, government CIO, said if there is a business case for IT spending it will be considered.
But he warned that regardless of who wins the general election, cuts in IT spending are inevitable.
