Answer:
Temporarily low and so supply a smaller quantity of labor.
Explanation:
Because workers see that their nominal wages are falling, but they fail to see that the price level of goods and services also has fallen by the same percentage (meaning that their real wage has not fallen, but stayed the same), they will likely believe that the reward for their labor is less, so they will have less incentive to work, supplying a smaller quantity of their labor force in the process.
