Members of the union Unison, which represents civilian police workers in South Yorkshire, have voted for industrial action over pay.
In a national ballot 59.6 per cent of members said they would go on strike and 79 per cent said they would take part in action short of a strike.
Union general secretary Dave Prentis said: “These results send a clear message that after two years of pay freeze and last year’s below inflation pay rise, police staff have had enough. And they are ready to take action.”
“We are calling on the police employers to return to the negotiating table to improve the current pay offer.”
Some 7,436 votes were cast.
