 (from Ch. 108 1/2, par. 7-152)Sec. 7-152.     Disability benefits - Amount.     The amount of the monthly  temporary and total and permanent disability benefits shall be 50% of the  participating employee's final rate of earnings on the date disability was  incurred, subject to the following adjustments:(a) If the participating employee has a reduced rate of earnings at the  time his employment ceases because of disability, the rate of earnings shall  be computed on the basis of his last 12 month period of full-time employment.(b) If the participating employee is eligible for a disability benefit  under the federal Social Security Act, the amount of monthly disability  benefits shall be reduced, but not to less than $10 a month, by the amount  he would be eligible to receive as a disability benefit under the federal  Social Security Act, whether or not because of service as a covered employee  under this Article.  The reduction shall be effective as of the month the  employee is eligible for Social Security disability benefits.  The Board  may make such reduction if it appears that the employee may be so eligible  pending determination of eligibility and make an appropriate adjustment  if necessary after such determination.  If the employee, because of his  refusal to accept rehabilitation services under the federal Rehabilitation  Act of 1973 or the federal Social Security Act, or because he is receiving  workers' compensation benefits, has his Social Security benefits reduced or  terminated, the disability benefit shall be reduced as if the employee were  receiving his full Social Security disability benefit.(c) If the employee (i) is over the age for a full Social Security  old-age insurance benefit, (ii) was not eligible for a Social  Security disability benefit immediately before reaching that age, and (iii) is eligible for a full Social Security old-age insurance  benefit, then the amount of the monthly disability benefit shall be  reduced, but not to less than $10 a month, by the amount of the old-age  insurance benefit to which the employee is entitled, whether or not the  employee applies for the Social Security old-age insurance benefit.  This  reduction shall be made in the month after the month in which the employee  attains the age for a full Social Security old-age insurance benefit.  However, if the employee was receiving a Social Security disability  benefit before reaching the age for a full Social Security old-age insurance  benefit, the disability benefits after that age  shall be determined under subsection (b) of this Section.(d) The amount of disability benefits shall not be reduced by reason of  any increase, other than one resulting from a correction in the employee's  wage records, in the amount of disability or old-age insurance benefits  under the federal Social Security Act which takes effect after the month  of the initial reduction under paragraph (b) or (c) of this Section.(e) If the employee in any month receives compensation from gainful  employment which is more than 25% of the final rate of earnings on which  his disability benefits are based, the temporary disability benefit payable  for that month shall be reduced by an amount equal to such excess.(f) An employee who has been disabled for at least 30 days may return to  work for the employer on a part-time basis for a trial work period of up to  one year, during which the disability shall be deemed to continue.  Service  credit shall continue to accrue and the disability benefit shall continue  to be paid during the trial work period, but the benefit shall be reduced  by the amount of earnings received by the disabled employee.  Return to  service on a full-time basis shall terminate the trial work period.  The  reduction under this subsection (f) shall be in lieu of the reduction, if  any, required under subsection (e).(g) Beginning January 1, 1988, every total and permanent disability benefit  shall be increased by 3% of the original amount of the benefit, not  compounded, on each January 1 following the later of (1) the date the total  and permanent disability benefit begins, or (2) the date the total and  permanent disability benefit would have begun if the employee had been paid  a temporary disability benefit for 30 months.
