MISHOR ADUMIM INDUSTRIAL ZONE, West Bank — The personal conflict that thousands of Palestinians face working for Israeli companies in the occupied West Bank is particularly stark for Hassan Jalaita, who for 18 years has repaired Israeli Army jeeps at the Zarfati garage here.

Those are the very same jeeps that confront Mr. Jalaita at the checkpoint he crosses each morning. The same ones that sweep through villages where his friends and relatives live. But those jeeps also help pay his $1,471 monthly salary at Zarfati, more than triple the minimum wage in Palestinian areas of the West Bank, where a 19 percent unemployment rate and lack of labor laws make finding a decent job difficult.

“I feel like I’m not a human being — we are serving the occupation,” said Mr. Jalaita, 47, a father of five, two of them university students. “I am forced to work here because I have a house, I have a family. Tomorrow, if there is another place to work, if there is work in Palestine, I will do it.”

Israeli industries operating in settlements that most of the world considers illegal and a prime obstacle to peace have become a focus of global attention in recent weeks, amid growing momentum for a boycott movement targeting Israeli businesses and institutions. The flash point was the actress Scarlett Johansson, who resigned her position with Oxfam, the antipoverty group, on Jan. 30 after Oxfam criticized her for signing on as a spokeswoman for SodaStream, the maker of home-carbonation systems whose largest factory is here in Mishor Adumim.
