Section 287.250 RSMo provides the framework for calculating an employee's average weekly wage, and provides, in relevant part, as follows:
- Except as otherwise provided for in this chapter, the method of computing an injured employee's average weekly earnings which will serve as the basis for compensation provided for in this chapter shall be as follows:
(4) If the wages were fixed by the day, hour, or by the output of the employee, the average weekly wage shall be computed by dividing by thirteen the wages earned while actually employed by the employer in each of the last thirteen calendar weeks immediately preceding the week in which the employee was injured or if actually employed by the employer for less than thirteen weeks, by the number of calendar weeks, or any portion of a week, during which the employee was actually employed by the employer. For purposes of computing the average weekly wage pursuant to this subdivision, absence of five regular or scheduled work days, even if not in the same calendar week, shall be considered as absence for a calendar week.
- If an employee is hired by the employer for less than the number of hours per week needed to be classified as a full-time or regular employee, benefits computed for purposes of this chapter for permanent partial disability, permanent total disability and death benefits shall be based upon the average weekly wage of a full-time or regular employee engaged by the employer to perform work of the same or similar nature and at the number of hours per week required by the employer to classify the employee as a full-time or regular employee, but such computation shall not be based on less than thirty hours per week.
Citing § 287.250.1(4) as the controlling statutory provision for determining employee's average weekly wage, the administrative law judge calculated employee's average hourly rate based on employer/insurer's wage statement showing employee's pay for the thirteen full pay periods prior to her July 15, 2014, injury. The administrative law judge excluded the pay period ending June 21, 2014, from her calculation because that period represented a time when employee was absent from work a significant amount of time. No party disputes the administrative law judge's calculation of employee's average hourly wage rate as $10.83.
The administrative law judge then found "Consistent with Claimant's testimony and all other evidence in this claim Claimant never worked 80 hours over a two-week term and

was clearly a part-time employee."1 Based on this finding the administrative law judge applied § 287.250.3 to calculate employee's average weekly wage. Noting that § 287.250.3 requires the use of at least thirty hours per week when determining the average weekly wage of a part-time employee, the administrative law judge concluded, "As the Court determined the Claimant's hourly rate to be 10.83, using the 30 hour rule, Claimant's average weekly wage is 324.90 resulting in a compensation rate of $216.60 for purposes of determining permanent partial disability."2
Employee testified that employer hired her as a part-time Certified Nursing Assistant (CNA) and that she worked between twenty and forty hours per week. She further testified that full-time CNAs worked forty hours per week. Employee's hearing testimony regarding the number of hours worked per week by full-time CNAs was uncontroverted.
We agree § 287.250.3 governs employee's average weekly wage, because employee was a part-time worker. However, we find no case law that supports the administrative law judge's apparent assumption that calculation of a part-time employee's average weekly wage under this provision, colloquially known as the "thirty-hour rule," must be limited to thirty hours. Such an interpretation is inconsistent with the plain language of the statute, which clearly states, "[S]uch computation shall not be based on less than thirty hours per week [emphasis added]."
In *Martin v. Mid-America Farm Lines, Inc.*, 769 S.W.2d 105 (Mo. Banc, 1989), in construing an earlier and substantially differently worded version of § 287.250, the court stated:
> The court of appeals held that the claimant's compensation should be computed on a reduced basis because she was a part-time employee. Our cases consistently hold that there is no distinction between full-time and part-time employees and that all injured employees are to be compensated on the basis of annualized earnings, in accordance with one of the subdivisions of § 287.250.
The court of appeals observed that, under the commission's award, this claimant stands to receive substantially more in compensation than she would have received in earnings had she not been injured. This concern is misplaced. The workers' compensation laws provide a substitute for the common law action which an employee might otherwise maintain against an employer. Workers' compensation is designed to provide compensation for loss of earning capacity, which is a proper element of common law damages and is allowable without regard to the time worked in the past, prospects for future employment, or plans for working in the future. If part time employees were relegated to reduced compensation they would not be made whole for their loss. *Id.* at 109.

Consistent with the public policy expressed in *Martin, supra*, encouraging equitable compensation rates for part and full-time employees, and the absence of any authority that expressly restricts calculation of a part-time employee's weekly wage to thirty hours per week, we find that a fair and just computation of employee's average weekly wage in this case should be based on the forty-hour work week of a full-time CNA.
Based on an average weekly wage of $433.20, pursuant to § 287.190.5(5), employee's compensation rate is $288.80 for purposes of determining permanent partial disability. Based on 10% of the body as a whole, employee is entitled to forty weeks of compensation. We modify the administrative law judge's award to allow employee 11,552.00 (288.80 X 40) for permanent partial disability benefits.
