Answer:
The union contract issue that deals with a cost-of-living adjustment is commonly referred to as "COLA" or "Cost-of-Living Adjustment." This provision in a union contract ensures that employees' wages or benefits are adjusted periodically to keep pace with inflation or changes in the cost of living. The purpose of a COLA is to maintain the purchasing power of employees' wages over time, as the cost of goods and services tends to increase. It helps to address the impact of inflation on employees' compensation and is typically negotiated between the union and the employer as part of the contract terms.
