1. (a) Any person receiving a disability retirement annuity may, without affecting payment of the annuity, be employed for a period not to exceed 90 days during any school year by public educational institution covered by TRS on as much as one-half the full time load for the particular position according to the personnel policies of the employer. Total substitute service under §31.33 of this chapter and half-time employment may not exceed 90 days during any school year. This exception does not apply for the first month after the retiree'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) or under §29.21 of this title (relating to Effective Date for Disability Retirement)).
2. (b) "One-half time" employment measured in clock hours must never exceed one-half of the time required for the full time position in a calendar month or 92 clock hours, whichever is less, and may not exceed a total of 90 days in a school year. Determination of one-half time will be made on a calendar month basis as the full time load may vary from month to month. Actual course instruction in state-supported colleges (including junior colleges), universities, and public schools shall not exceed during any month one-half the normal load for full-time employment at the same teaching level.
3. (c) "One-half time" employment for bus drivers shall in no case exceed 12 days in any calendar month. Work by a bus driver for any part of a day shall count as a full day for purposes of this section.
