Marx recognized two distinct but also interrelated processes of increasing surplus-value extraction: absolute and relative surplus-value. Both these processes hinge upon the duration, the intensity and the productivity of labour, albeit in different ways. The increase of the duration of labour is indisputably related to absolute surplus-value and the increase of labour productivity to relative surplus-value. However, there is controversy regarding the position of the intensity of labour. Marx's argument that it belongs to relative surplus-value is disputed by many Marxists. This paper argues that Marx's thesis is correct because the intensification of labour and the increase of its duration are ultimately two opposing trends and thus should not be coupled in the same concept.

During the last decades an increase of unpaid overtime has been observed combined with the inversion of the working time decreasing trend. This article analyses the data from the Labour Force Survey to estimate the determinants of unpaid overtime in Greece and uses the results to test various theoretical explanations.
