Civil servants will end a three-month campaign of strikes and other forms of industrial action over pay, jobs, pensions and working conditions with demonstrations in the West Midlands and across the country.

Members of the Public and Commercial Services Union ( PCS ) will stage lunchtime events in towns and cities on Thursday, including Birmingham and Dudley as well as Cardiff, Peterborough, Preston, Liverpool, Manchester and Plymouth and outside the Treasury in London.

The union launched a national strike of its 250,000 members on Budget Day in March and has since called waves of industrial action affecting different Government departments and agencies across the UK.

The PCS is campaigning against Government policies on the civil service, which it says has led to cuts in pay, pensions and jobs as well as terms and conditions.

The union will now consult with its members on the next stage of its campaign, holding meetings in more than 800 of its branches over the summer.

Commenting ahead of Wednesday's Government Spending Review, general secretary Mark Serwotka said: "With our economy in the longest slump since the 1870s, George Osborne has been a catastrophic failure as Chancellor yet he is set to plough on regardless with another round of cuts.

"With £50 billion cut from workers' wages every year since the recession and half a million people now relying on food banks to get by, this Government's plan was clearly never about balancing the books. It was about remoulding society and rolling back years of progress.

"But Osborne has failed even by his own measures, with the UK losing his prized AAA credit rating and only narrowly avoiding a triple-dip recession. This downgraded Chancellor must stop the cuts and start investing to breathe life back into our economy and help our struggling communities."
