at the initial start of the program were not the only ones affected by this operation, there were also massive groups of workers who felt the need to extend their stay in the U.S. well after their labor contracts were terminated. In the first year, over a million Mexicans were sent back to Mexico; 3.8 million were repatriated when the operation was finished. The criticisms of unions and churches made their way to the U.S. Department of Labor, as they lamented that the braceros were negatively affecting the U.S. farmworkers in the 1950s. In 1955, the AFL and CIO spokesman testified before a Congressional committee against the program, citing lack of enforcement of pay standards by the Labor Department. The Department of Labor eventually acted upon these criticisms and began closing numerous bracero camps in 1957–1958, they also imposed new minimum wage standards and in 1959 they demanded that American workers recruited through the Employment Service be entitled to the same wages and benefits as the braceros. The Department of Labor continued to try to get more pro-worker regulations passed, however the only one that was written into law was the one guaranteeing U.S. workers the same benefits as the braceros, which was signed in 1961 by President Kennedy as an extension of Public Law 78. After signing, Kennedy said, "I am aware ... of the serious impact in Mexico if many thousands of workers employed in this country were summarily deprived of this much-needed employment." Thereupon, bracero employment plummeted; going from 437,000 workers in 1959 to 186,000 in 1963. During a 1963 debate over extension, the House of Representatives rejected an extension of the program. However, the Senate approved an extension that required U.S. workers to receive the same non-wage benefits as braceros. The House responded with a final one-year extension of the program without the non-wage benefits, and the Bracero Program saw its demise in 1964. United States Emergency Farm Labor Program and federal public laws 1942-1947 Emergency Farm Labor Supply Program 1948-1964 Farm Labor Supply Program The workers who participated in the bracero program have generated significant local and international struggles challenging the U.S. government and Mexican government to identify and return 10 percent mandatory deductions taken from their pay, from 1942 to 1948, for savings accounts that they were legally guaranteed to receive upon their return to Mexico at the conclusion of their contracts.
