Individual workers' wages are recorded on the DES wage record files and retained for five quarters to be used for determining monetary benefit entitlement should a worker file a claim for unemployment insurance benefits. The DES is required to establish and maintain a separate experience rate account for each employer.
In the United States and formerly Canada a ton is defined to be 2,000 pounds (907 kg). Where confusion is possible, the 2240 lb ton is called long ton and the 2000 lb ton short ton; the tonne is distinguished by its spelling, but usually pronounced the same as ton, hence the US term metric ton.
In the United States, a short ton is usually known simply as a ton, without distinguishing it from the tonne (1,000 kilograms or 2,204.62262 pounds), known there as the metric ton, Imperial ton, or the long ton (2,240 pounds or 1,016.0469088 kilograms).
