With the oligarchy split, there won't be a consensus to repress. Better to give a little, and buy social peace, than to lose everything through intransigence. That little goes a long way in E1 Salvador. If there is less repression, the public sector unions can win a place in the newly privatized state enterprises. Garment workers can organize unions and begin improving conditions in the factories.
Repression is the key issue in building democracy, as the peace accords' negotiators understood.
Repression is a key issue in building a global solidarity movement to tame transnational corporations. But it takes a tremendous amount of repression to keep wages low, conditions inhuman, and workers un-unionized. Lift the repression, and workers can organize, leaving the TNCs nowhere to run. So has the labor movement. The third part, the global organization, needs to be created.
