Workers at Canberra's water provider will stop work for two hours on Wednesday morning over a pay dispute with management.
The union representing Icon Water workers has called on the ACT government to intervene in negotiations, saying the pay offer from the company does not keep pace with the cost of living.
Workers have been offered a 12 per cent pay rise over four years, which is 3 per cent a year. Workers have called for a 15 per cent rise over three years.
