The take over of their work places by workers has happened throughout the last 100 years during political, economic or social crisis?. In most take over?s workers have not only demonstrated that they are able to run factories, services and institutions, they also acted far beyond the need to maintain their jobs and experimented and created new ways of how to work and new relations among themselves, with other workers and with communities. During the last years we have seen again hundreds if not thousands occupations of work places, especially in Latin America, but also a few one in the North of the world. Facing a financial and systemic crisis these occupations are likely to grow in the near future as a mechanism of defense against the destructive force of capitalism. In this panel we want to have a look at the history and the actuality of workers control, discussing success and problems of workers control.
