HONOLULU -- The union that represents Hawaiian Electric Co. workers has told its members it has given the company a 48-hour strike notice.

On Tuesday, the union met with HECO negotiators. However, no new agreement has been reached.

Members of the International Brotherhood of Electrical Workers Local 1260 rejected a contract offer by HECO.

Contracts between the IBEW represent 1,200 employees at HECO, Maui Electric Co. and Hawaii Electric Light Co.

The union has said it opposes management's proposal to require employees to work two more years to get full retirement benefits, pushing back their retirement age to 62 from 60.

The union has said it also is against a management effort to create two tiers of wage increases, giving a smaller pay hike to office personnel and a higher raise for HECO crews that work in the field.
