It sounds like my "easy" fix is to stop the practice of offering previously waived PT employees with continuing eligibility the opportunity to enroll at the mid-year eligibility review window. Someone first gaining eligibility could make an election; someone losing eligibility could have their election revoked; but someone currently waived with continuing eligibility could make an election change ONLY based on a QE, but not just because it's our mid-year eligibility review and they are still eligible.
