We don't employ Arabs - so dozens of companies listed in Israel's Yellow Pages plainly state. The businesses, which include a bus firm, plumbers, electricians and a removal firm, openly advertise under the banner of "Hebrew labour" - a policy to hire only Jews that Israeli civil rights groups say is a violation of the country's anti-discrimination laws. The groups believe such advertising is one of a series of initiatives that aim to give preferential treatment to Jewish job-seekers over the country's Arab citizens, a fifth of the population...Civil rights groups have long complained that Israel's anti- discrimination employment laws are rarely enforced. The government responded in 2008 by establishing a Commission for Equality in Employment. But Jafar Farah, director of the Mossawa Centre, an advocacy group for Israel's Arab minority, said the commission, police and government bodies were "unwilling" to enforce laws when discrimination occurred against Arabs.
