It is well known that labor migrants from different countries all over the Eurasian Union are the backbone of crucial economy sectors in the Russian Federation as, inter alia, construction, agriculture or trade. This article deals with another less mentioned but similarly significant labor market, which substantially changed its assemblage during the last couple of years, namely commercial urban transport services. In the last two decades, the marshrutka sector underwent major reforms and formalization processes that, on the one hand, brought operators back into the tax net and ensured a certain extension of control to the local transportation departments but, on the other hand, worsened the labor conditions of the transportation workers. Drawing from the empirical evidence of my fieldwork in southern Russia, I describe currently problematized mobility assemblages and embed the actor’s articulations in broader conflicts within the marshrutka business and transportation regulation policy. I further analyze how labor migrants have been forced to accept unfavorable working conditions in the enterprises as a direct result of politically triggered reforms in the marshrutka business. The paper provides insights into the social arena of the marshrutka, which serves as a societal encounter of urban conflicts and transformation mirroring (un-)intended effects of the local transportation reformation attempts.
