1. (a) Any person receiving a service retirement annuity who retired after January 1, 2011, may work in a month as a substitute in a public educational institution without forfeiting the annuity payment for that month.
2. (b) Employment by a third party entity is considered employment by a Texas public educational institution unless the retiree does not perform duties or provide services on behalf of or for the benefit of the institution or the retiree was first employed by the third party entity before May 24, 2003, and may not be combined with the substitute service exception without forfeiting the annuity payment except as provided in this chapter.
3. (c) A person working under the exception described in this section is not separated from service with all Texas public educational institutions for the purpose of the required 12 full consecutive month break described in §31.15 of this title (relating to Full-time Employment after 12-Consecutive-Month Break in Service).
4. (d) The exception described in this section and the exception for one-half time employment described in §31.14 of this title (relating to One-half Time Employment) may be used during the same school year. If the substitute service and the other employment occur in the same calendar month, the total amount of time that the retiree works in both positions may not exceed the amount of time available that month for work on a one-half time basis. Beginning September 1, 2011 and thereafter, the exception for substitute service under this section and the exception for one-half time employment under §31.14 of this title may be used during the same calendar month without forfeiting the annuity only if the total number of days that the retiree works in those positions in that month does not exceed one-half the number of days available for that month for work. If the calendar month has an odd number of work days available for work, the retiree is limited to working only the number of whole days available and may not work any amount of additional time in the one-half day remaining when dividing the total number of work days in the month by 2 without forfeiting the annuity for that month.
5. (e) The exception described in this section does not apply for the first month after the person's effective date of retirement (or the first two months if the person's retirement date has been set on May 31 under §29.14 of this title (relating to Eligibility for Retirement at the End of May)).
6. (f) A retiree who reports for duty as a daily substitute during any day and works any portion of that day shall be considered to have worked one day.
