This work analyzes the neoliberal health sector reforms that have taken place in Latin America, the preparation of health care workers for the reforms, the reforms’ impacts on the workers, and the consequences that the reforms have had on efficiency and quality in the health sector. The piece also looksat the process of formulating and implementing the reforms. The piece utilizes secondary sources and in-depth interviews with health sector managers in Bolivia, Colombia, Costa Rica, the Dominican Republic, Ecuador, El Salvador, and Mexico. Neoliberal reforms have not solved the human resources problems that health sector evaluations and academic studies had identified as the leading causes of health system inefficiency and low-quality services that existed before the reforms. The reforms worsened the situation by putting new pressures on health personnel, in terms of both the lack of necessary training to face the challenges that came with the reforms and efforts to take away from workers the rights and benefits that they had gained during years of struggles by unions, and to replace them with temporary contracts, reduced job security, and lower benefits. The secrecy with which the reforms were developed and applied made workers even more unified. In response, unions opposed the reforms, and in some countries they were able to delay the reforms. The neoliberal reforms have not improved the efficiency or quality of health systems in Latin America despite the resources that have been invested. Nor have the neoliberal reforms supported specific changes that have been applied in the public sector and that have demonstrated their ability to solve important health problems. These specific changes have produced better results than the neoliberal reforms, and at a lower cost
