An arbitrator has awarded raises of more than 2 percent for each of the next two years to Hawaii firefighters in a binding decision that may be the bellwether of ongoing contract negotiations with all of the state and county public worker unions this year. Hawaii Fire Fighters Association President Robert “Bobby” Lee said the decision earlier this week also continues with salary step movement salary increases every three years for fire fighters based on their employment anniversaries. That means about two-thirds of the union’s 2,000 members will get an extra step movement pay increase worth roughly 1 percent during the new two-year contract.
