One of the most significant changes in the mining industry globally has been the end of the ‘mining city’ model. Since more than two decades ago, it has been replaced by a ‘hotel’ model, in which workers sleep while in the camp, leaving their families away from the mining settlement for several days. This Article has three objectives. First, to place this transformation in the broader context of changes in the Latin American mining industry. Second, to summarise, on the basis of my previous investigations, the paths through which this system has undermined the traditional strategies of mining trade unions in Peru. Finally, to argue that, despite these transformations, workers are not passive actors to the new arrangements, but have developed new forms of action, albeit with variations depending on the local and national contexts in which they occur.
