Cost-of-living adjustment 
The eighth regular cost-of-living adjustment under the National Agreement will be $790 annually based on the Consumer Price Index for Urban Wage Earners and Clerical Workers (CPI-W) for July announced August 16 by the U.S. Bureau of Labor Statistics.

The cost-of-living adjustment, effective the pay period beginning September 9 (pay date September 29), is the final regular COLA included in the 2001-2006 contract. It was based on the increase in the CPI-W between January and July 2006.

The eighth COLA of $790 annually is equivalent to 38 cents per hour, or $30.40 per pay period.

The latest COLA raised the annual pay for top rate carriers (CC Grade 1, Step O) to $49,218 annually, an increase of $6,583 or $253.19 per pay period since the beginning of the contract.

COLAs have accounted for over 50 percent of the total increase in salary.
