Capita pensions staff are considering strike action after voting to reject the introduction of a performance-related pay system at the outsourcing firm.
In an independent ballot, Unite members across Capita voted by 88.4 per cent to reject the pay proposal on a turnout of 72 per cent.
A unite spokesman says the proposed pay system would pit worker against worker rather than introducing an objective pay rise.
Pensions employees in Glasgow, Bristol and Reading are affected by the action.
The spokesman says: “This is specifically for Capita workers in the pensions division. It is only in the finance division of Capita that there is union recognition and these talks take place.”
Capita says it has not received formal notification of a ballot for strike action.
However, Unite says because Capita has not yet made a counter-offer, the union will serve it with a seven-day notice for a final industrial ballot for strike action that will be launched in the coming days.
Unite finance national officer Dominic Hook says: “There is still time for Capita to return to the table with a sensible offer reflecting the hard work of our members which has made the company so profitable.”
In 2013 Capita members took successful strike action over pay following a 65 per cent rejection of the proposed deal.
