In August, the first month of the six-month adjustment period for the fifth COLA under the 2024 Agreement, the CPI-W Unadjusted Index (1967=100) rose from last month to 978.445, an increase over the July 2026 index point upon which employees received the last COLA.
If the adjustment was made based on the August 2026 Index, the adjustment would be:
| Monthly Tracking | Amount |
| Per Annum | $208.00 |
| Per Pay Period | $8.00 |
| Cents Per Hour | $0.10 |
However, the fifth COLA under the 2024 National Agreement will be based on the January 2027 Index. Currently, the BLS has not announced the 2027 CPI release dates, so the effective dates have not yet been determined.
Under the 2024-2027 National Agreement, employees accrued the following adjustments totaling $2,870.00:
| # | Amount | Effective Date | Pay Period | Pay Date |
| 1 | $395.00 | March 08, 2025 | 07-2025 | March 28, 2025 |
| 2 | $811.00 | September 06, 2025 | 20-2025 | September 26, 2025 |
| 3 | $250.00 | March 07, 2026 | 07-2026 | March 27, 2026 |
