Employee Christopher Berry seeks review, by writ of certiorari, of the decision by the Worker’s Compensation Court of Appeals affirming the compensation judge’s calculation of his average weekly wage. Though we reverse in part the basis of decision, we find no miscalculation.
On April 25, 1988 Employee, 34, an experienced roofer, commenced employment as a roofer with Daak Construction. Only hours after beginning work, Berry fell from a roof at his job site and suffered neck and back injuries. His injuries resulted in medical restrictions that made it impossible for him to return to his previous employment as a roofer. Daak’s insurer, Farm Bureau Mutual, admitted liability and commenced payment of temporary total disability payments based on a pre-injury average weekly wage of $300.
Berry filed a claim petition alleging a pre-injury average weekly wage of $480 and corresponding underpayment of benefits. He argued that, because he was a construction worker, his average weekly wage should be determined by calculating his daily wage and multiplying it by five pursuant to Minn.Stat. § 176.011, subd. 3. He also contended that his daily wage could be extrapolated from his performance during the few hours he worked for Daak prior to his injury.
The compensation judge rejected both claims. She determined that Berry had failed to prove that he was engaged in employment where the hours of work are affected by “seasonal conditions” as required by the statute and that there was inadequate evidence from which to extrapolate Berry’s actual wage-earning capacity. She therefore calculated Berry’s weekly wage by averaging the weekly wages of three of Berry’s co-worker’s at Daak who were employed doing similar work. Em *314 ployee’s weekly wage was determined to be $315.82 resulting in a base compensation rate of $210.55 per week. Berry appealed and the WCCA affirmed the decision of the compensation judge with respect to wage calculation.
Berry raises two issues on appeal: (1) Whether the weekly wage for an employee in the construction industry is, as a matter of law, calculated at not less than five times the daily wage under Minn.Stat. § 176.011, subd. 3, without additional proof that the employee’s particular employment is in an industry where hours of work are affected by seasonal conditions, and (2) whether the compensation judge properly calculated the employee’s average weekly wage based on the earning records of other employees engaged in similar work when the employee had only worked for a fraction of one day prior to the injury giving rise to compensation.
1. In Minnesota, worker’s compensation wage loss benefits are generally determined by calculating two-thirds of the “average weekly wage.” Minn.Stat. § 176.-101, subd. 1 (1990). In most cases, weekly wage is determined by multiplying the daily wage by the number of days normally worked in the business of the employer. Minn.Stat. § 176.011, subd. 18. The Worker’s Compensation Act contains a special provision, however, that “... in the case of the construction industry, mining industry, or other industry where the hours of work are affected by seasonal conditions, the weekly wage shall not be less than five times the daily wage.” Minn.Stat. § 176.-011, subd. 3. In essence, the legislature imputes a full time wage basis to workers in certain industries. The parameters of that imputed full-time wage provision are in dispute here.
Berry was employed as a roofer at the time of the injury and neither party disputes that roofing is a part of the construction industry. He contends that because he is a construction worker he is entitled to application of the five-day wage provision as a matter of law without having to prove that his specific employment is “seasonal” in nature.
The decisions of this court and those of the WCCA are not entirely consistent with respect to proper interpretation and application of the full-time wage provision. Some of the cases have appeared to place a burden on the construction worker to prove employment in an industry where “hours of work are affected by seasonal conditions.”
See Olsen v, Kling,
Other decisions, however, have indicated that the provision applies as a matter of law.
Bradley v. Vic’s Welding,
The plain language of Minn.Stat. § 176.-011, subd. 3 supports Berry’s assertion that the provision applies to the construction industry as a matter of law. The statute reads “in the case of the construction industry, mining industry,
or
other industry where the hours of work are affected by seasonal conditions_” Minn.Stat. § 176.011, subd. 3 (emphasis added). The use of the disjunctive rather than the conjunctive denotes legislative intent to apply the seasonal conditions provision to the construction and mining industries as a matter of law and to leave open the possibility of its application to other industries, subject to additional proof that the indus

try in question is one in which the hours of work are “affected by seasonal conditions.”

§ 21.14 (4th ed. 1985). Any other interpretation would render the enumeration of specific categories meaningless.
See Ford v. Willis J. Kruckeberg Roofing & Sheet Metal,
We reject Respondent Daak’s argument that the legislature intended the full-time wage provision to apply only to industries such as open pit mining that actually cease operations during the winter months and not to industries where hours are made irregular by inclement weather or seasonal slumps. In
Rogers v. Cedar Van Lines, Inc.,
We therefore reverse the WCCA and hold that the weekly wage for an employee in the construction industry is, as a matter of law, calculated at not less than five times the daily wage under Minn.Stat. § 176.011, subd. 3, without additional proof that the employee’s particular employment is in an industry where hours of work are affected by seasonal conditions.
We note that while our decision on this point clarifies the law, it does not affect the employee’s wage calculation in this particular case. As discussed below, the compensation judge calculated Berry’s weekly wage by averaging the weekly wage records of three full-time co-employees. The wage determination was therefore based on full-time employment and was roughly equivalent to “five times the daily wage.”
2. Because the employee had worked for the employer for less than half a day, the compensation judge, citing

The object of wage determination is to “arrive at a fair approximation of [the employee’s] probable future earning power which has been impaired or destroyed because of the injury.”
