Palestinian labor flows to Israel have been very large, and have accounted for a significant proportion of overall Palestinian employment and GNP. This book examines the flow of Palestinian labor to Israel over the last three decades, and shows how it has fluctuated over time, with, most recently, a shift in the flow towards Israeli settlements in the occupied territories. It argues that the nature of Palestinian labor flows demonstrates that the territorial dimension to the Israeli-Palestinian conflict can not be separated from evolving economic and labor realities; and that recent changes have transformed the occupied Palestinian territories into population reservoirs that are unsustainable economically nor able to separate viably from Israel to form an independent contiguous Palestinian state.
