G.R. No. 128845 June 1, 2000
International School is a domestic educational institution established primarily for dependents of foreign diplomatic personnel and other temporary residents. The School hires both foreign and local teachers as members of its faculty – they are classified as (1) foreign-hires and (2) local-hires.
The School grants foreign-hires certain benefits not accorded local-hires. These include housing, transportation, shipping costs, taxes, and home leave travel allowance. Foreign-hires are also paid a salary rate twenty-five percent (25%) more than local-hires. The School justifies the difference on two “significant economic disadvantages” foreign-hires have to endure.
