cheap flights travel: Union warns of 'prolonged action'

More than a million council workers went on strike in 2006 against changes to their pensions

The UK's biggest public sector union, Unison, has warned that it is "on the road to industrial action" over changes to public sector pensions.

Its general secretary, Dave Prentis, said there would be sustained strike action this autumn if a deal can't be reached with the government.

A TUC delegation and the government have having talks since February. A final meeting is scheduled for 28 June.

If there is no agreement, Mr Prentis said Unison would ballot its members.

Mr Prentis has been leading the talks for the unions alongside Brendan Barber, general secretary of the TUC.

But he said those discussions were not going well: "We haven't made any progress really on the big issues", he said.

In order to try to reduce the rising cost of public sector pensions, the government is seeking a 3% increase in employee pension contributions, which amounts to a doubling for many public sector staff.

The government did not comment on Mr Prentis' comments.

Unions say that plans under discussion also include reducing pension benefits and expecting staff to work for longer.

Mr Prentis said he thought his members would vote for strike action if a ballot was called

Speaking ahead of Unison's annual conference next week in Manchester, Mr Prentis said the union was preparing the membership register for a ballot which would be one of the biggest undertaken in the UK.

Balloting would take several weeks but he is convinced its outcome is assured.

"I've got no doubt whatsoever that everything is being put in place to enable us to win the ballot," he said.

Mr Prentis said the union was looking at how to ensure that the industrial action was sustainable. "This will be a major dispute," he said.

"It will not be one day of action - it will be long-term industrial action throughout our public services to prevent destruction of our pension schemes."

Unison represents 1.3 million workers across in areas including local government, health care, education and the voluntary sector.

Separately, 750,000 public sector workers are already due to strike on June 30th.

On Tuesday the National Union of Teachers (NUT) and the Association of Teachers and Lecturers ( ATL ) will reveal the result of their ballot for industrial action over pension changes.

The following day the Public and Commercial Services Union (PCS) will publish the result of its ballot over jobs, pensions and pay.
