Nasser also attempted to maintain oversight of the country's civil service to prevent it from inflating and consequently becoming a burden to the state. New laws provided workers with a minimum wage, profit shares, free education, free health care, reduced working hours, and encouragement to participate in management. Land reforms guaranteed the security of tenant farmers, promoted agricultural growth, and reduced rural poverty. As a result of the 1962 measures, government ownership of Egyptian business reached 51 percent, and the National Union was renamed the Arab Socialist Union (ASU). With these measures came more domestic repression, as thousands of Islamists were imprisoned, including dozens of military officers. Nasser's tilt toward a Soviet-style system led his aides Boghdadi and Hussein el-Shafei to submit their resignations in protest.
