Ala. Code § 45-37A-51.102: Purpose.

The general purpose of the system embraced in this subpart is the governmental one of promoting efficiency of employees in the service by partially relieving their minds of harassing fear of the consequences of loss of employment through disability, old age, and otherwise, and of other adverse circumstances surrounding the foregoing; and by furnishing trained employees a partial incentive to remain in the service thereby presumptively increasing efficiency.
