Talks have broken off as a strike continues by more than 300 unionized water workers in Halifax.

Halifax Water spokesman James Campbell says the talks were mounted soon after the strike began Tuesday, but broke off after several hours after a proposal by management was rejected by the union.

But the Canadian Union of Public Employees says no new proposals were put forward.

Changes to employee pensions is the main issue in the dispute.

The workers, including 230 outside and 105 inside workers, are represented by CUPE Locals 227 and 1431.
