Conceptualizing informalization as an effort to contribute to the exploration of collective bargaining strategy reminds a challenge for activists. Based on case studies in several countries in Southeast Asia, the paper tries to elaborate informalization by emphasizing salient elements depicting the position of working people amidst informalization. Political collective bargaining is not a new discourse in the social movement. Within the historical context, a wide variety of account has been produced to highlight the urgency of political struggle of working people to counter social power of capital. The prevailing fact of capital gaining its social power through circulation of money has been undisputed. Thus, here, informalization is elaborated in the context of capital as a process continuously assembled to expand the profit making and sustain the social power over society. The political collective bargaining here is beyond the regulatory framework. It focuses on the process how working people reclaim their political space and power.
