"This law aims to create a new reality among our people based on religion and not national identity," Palestine Liberation Organization executive committee member Hanan Ashrawi said in a statement.
Israel's parliament on Monday passed into law a bill expanding the equal opportunities commission from five to 10 members, and giving separate seats for the first time to representatives of Christian and Muslim Arab workers' groups.
"We and the Christians have a lot in common. They’re our natural allies, a counterweight to the Muslims who want to destroy the country from within," Haaretz daily quoted the bill's sponsor, Yariv Levin, of Prime Minister Benjamin Netanyahu's
party, as saying.
It also sets aside seats for Druze, ultra-Orthodox Jews and families of Jewish immigrants from Ethiopia, all groups which have higher than average unemployment.
The bill was passed three months ahead of the first trip to the Holy Land by Pope Francis, who is to visit
Amman, Bethlehem, and Jerusalem from May 24 to 26.
The Palestinian Israeli community has its roots in the 160,000 Palestinians who remained inside Israel
following its creation in 1948. Today they and their descendants number around 1.3 million out of a total Israeli population of 7.9 million.
Palestinian Israelis have full citizenship and are allowed to vote, but have long complained of official discrimination.
