8. XYZ International School, Inc. was a domestic educational institution established primarily for dependents of foreign diplomatic personnel and other temporary residents. It classified its teachers into two categories: (1) foreign hires; and (2) local hires. The salary of foreign hires was 25% higher than those of local hires. The local hires complained that this policy was allegedly discriminatory since both groups perform the same work. XYZ International School, Inc. countered that the policy was adopted to attract foreign hires and that the two groups are not similarly situated. Decide with reason(s).
