Under the terms of the 2010 National Agreement, the COLA triggered by the release of the July 2012 CPI-W will be effective the second full pay period following the release of the July 2013 index. The expected effective date will be Sept. 7, 2013 (Pay Period 20-2013).

Note: The 1st COLA under the 2010 National Agreement will be $62 per year (3 cents per hour or $2.40 per pay period).
