More than a million public sector workers are set to take strike action in the autumn unless the Government pulls back from its controversial pension changes, Dave Prentis, general secretary of Unison, has warned today. He said huge numbers of local government workers were "on the road" to industrial action, with balloting of around 1.2 million workers set to start soon. Mr Prentis said the Government was now on a "collision course" with public sector unions over pensions as well as cuts to jobs, pay and services. He told a press conference: "It will not be one day of action - it will be long-term industrial action throughout all our public services.”. Using Council Services could risk severe disruption/delay to key projects at a time when the construction industry is just starting to show signs of emerging from the recession. Given the threat from Unison, we would advise Architects and Contractors about to submit Building Control applications to think twice about using Local Authority Building Control services and use private sector suppliers instead. Also in order to safeguard the house-building programme Government should look again at the privatisation of the processing of planning applications.
