If the workers of a firm successfully negotiate an increase in wages, which of the following is most likely to happen? a. The demand curve for the product the firm produces shifts rightward. b. The demand curve for the product the firm produces shifts leftward. c. The supply curve of the product the firm produces shifts rightward. d. The supply curve of the product the firm produces shifts leftward.

This will cause the supply to decrease. The decrease in supply will cause the supply curve to shift to the left.
