After decades of fringe existence in economic and development policy debates, social protection and social justice have experienced a renaissance in global policy debates. This has opened up a window of opportunity for political actors who promote social justice on a national and international level. Such actors can be found in civil society organisations and trade unions. However, the window is closing rapidly, as the echos of past neo-classical economic and fiscal policies are resurfacing. This short article has four key messages: there is a historical chance to make a difference, as we have a policy instrument that is carried by global consensus, it is time to work together, time is running out, and hence the time to act is now.
