The Philippine Overseas Employment Administration (POEA) said Israel plans to impose a tax on Filipinos and other foreign workers.
"The strong preference for foreign workers may be the reason behind the plan of the Israeli government to tax foreign workers," the POEA said.
The POEA said the Israeli government was considering the move to tax foreign workers to encourage employers to hire Israelis instead as foreign workers would become expensive.
However, Philippine embassy and labor officials in Israel said the imposition of the tax would not adversely affect the deployment of Filipino workers who are employed as caregivers.
Many Filipinos work as caregivers in Israel.
Last month, Hong Kong imposed a cut on the monthly pay of Filipino maids as part of a new government policy to tax all foreign workers.
Foreign Affairs Secretary Blas Ople said it was "a very serious act of discrimination" to ask maids from poor Southeast Asian countries to "disproportionately" shoulder the burden of narrowing Hong Kong’s ballooning budget deficit.
"Such a tax or levy is dreadful, it’s unfair and unwise," he said at a press conference at the Philippine consulate in Hong Kong.
"In times of economic difficulties, the pain should not be put on frail shoulders of those least able to bear it. (It is) unwise because foreign domestic helpers liberate Hong Kong women from their household chores and allow them to be active contributors to the housing economy."
In a statement, the Department of Foreign Affairs said Ople has instructed Consul General to Hong Kong Victoria Bataclan to work with other affected countries to appeal to the Hong Kong government to set aside the plan.
Last December, Labor and Employment Secretary Patricia Sto. Tomas said Filipino maids may be retrained as caregivers so they could work in Europe, Canada and the United States.
The Philippines had threatened to seek mediation from the International Labor Organization (ILO) to stop Hong Kong from cutting the pay of Filipino and other foreign domestic helpers.
