[...] Labour is a necessarily alienated form of work, in which humans do not control and own the means and results of production. It is a historic form of the organization of work in class societies. Work in contrast is a much more general concept common to all societies. It is a process, in which humans make use of technologies for transforming nature and society in such a way that goods and services are created that satisfy human needs. [...] The realm of freedom really begins only where labour, which is a form of work that is determined by necessity and external expediency, ends.
