In addition to any compensation heretofore provided by law for the poll workers in Chilton County, each poll worker shall be entitled to a twenty-two dollar ($22) per working day increase in such compensation with such increase to be paid in the usual manner from the county general fund. Provided further, that in addition to such increase, the returning officer shall receive an extra ten dollars ($10) per working day to be paid in like manner. In the event such poll workers are further compensated by the enactment of a general law providing compensation for poll workers throughout the state, the increases herein provided shall be granted only to the extent that such general law compensation for such workers fails to equal the county increases provided herein.
