Dailey v. Ferguson/Florissant Sch. Dist., 733 S.W.2d 861 (Mo. App.). (1989) Pension credit may not be denied for periods in which teacher received military service retirement credit. Federal statute which provides the retirement credits due a reservist under federal law cannot be excluded in determining eligibility for civilian employment pension benefits under any other law preempts Missouri law.
