Employees of the United Nations agency for Palestinians went on strike in the Gaza Strip on Monday to protest pay cuts and dismissals. The one-day strike closed more than 250 UNRWA schools in Gaza, as well as medical centers and food aid distribution points. The United States has traditionally been UNRWAs largest funder, providing around $350 million a year. But President Donald Trump has cut all support, sparking a funding crisis. The deficit caused 113 emergency program jobs to be scrapped and 584 staff positions were converted to part-time. More than 250 jobs have been cut in Gaza and the West Bank so far, while hundreds of full-time roles have become part-time. The refugee agencys labor union is demanding the job cuts be reversed and its leaders say the strike could be the first of a number of measures. A small protest took place outside the agencys Gaza headquarters. "The strike comes in light of the (UNRWA) administrations lack of responsiveness to the demands of the employees union and their insistence on not solving their problems," Amal al-Batsh, deputy head of the union, said in a statement. UNRWA says the funding deficit caused by the Trump administrations withdrawal of support is so severe cuts are unavoidable. Around 13,000 people work for the agency in Gaza, where more than two-thirds of the roughly two million residents are eligible for aid. UNRWA says more than 200,000 Palestinians attend its schools in the strip.
