Glasgow City Council Workers Vote To Go On Strike
Council workers have voted to go on strike in a dispute over pay.
Members of the GMB union at Glasgow City Council backed walkouts by 72% and other forms of industrial action by more than 4-1.
The union is in dispute over changes to working time arrangements, including plans to convert public holidays into annual leave, which it says could cost workers up to #500 a year.
It said it will notify the council of strike dates, warning that the action will hit key services including cleansing, refuse, land and environment, bereavement and social care.
Benny Rankin, a GMB Scotland officer, said: "Our members are taking a stand to resist the threat of poverty pay and to fight for decent public services under public ownership for the next generation.
"It is the lowest paid across the council who are bearing the brunt of the Scottish government's austerity agenda, with £130 million worth of cuts to the city's budget expected over the next two years.
"Time and again we have told the council that our members cannot sustain these cuts and that the holiday imposition would force a dispute.
"Perhaps now they will take their employees' concerns seriously and finally recognise the severity of this situation.''
