The Zionist movement tried to find work for the new immigrants who arrived in the Second Aliyah. However, most were middle class and were not physically fit or knowledgeable in agricultural work. The Jewish plantation owners had previously hired Arab workers who accepted low wages and were very familiar with agriculture. The leaders of the Zionist movement insisted that plantation owners (those who arrived in the First Aliyah) only hire Jewish workers and grant higher wages. The conquest of labor was a major Zionist goal. However, this caused some turmoil in the Yishuv for there were those who felt that they were discriminating against the Arabs just as they had been discriminated against in Russia. The Arabs became bitter from the discrimination despite the small number of Arabs that were affected by this.
