Toward the end of our earlier introduction to surplus value, the heart and motor of the class struggle, we wrote that: “The rate of surplus value for the capitalist is the rate of exploitation for the worker. By merely prolonging the working day, the capitalist accrues more (absolute) surplus value. Increasing the working day from eight to 10 hours results in two more hours of surplus value for the capitalist and of exploitation for the worker”. For any working period—whether it be a day, an hour, or five minutes—part of the period is “necessary labor” and another part is “surplus labor.” The former is when the worker produces the value of their own wage, and the latter is when the worker produces surplus value for the capitalist. The ratio between the two is the rate of surplus value for the capitalist and the rate of exploitation for the worker. Absolute surplus value, Marx says, is “produced by prolongation of the working-day” [2]. In other words, if the ratio between necessary and surplus labor is fixed, then prolonging the working day will result in more surplus value for the capitalist and a greater degree of exploitation for the worker. Capital’s entire reason for being is to produce surplus value, to increase the exploitation of the working class. As a result, there’s a logical impulse for each capitalist to extend the working day as much as possible. Yet not only might this produce problems for capitalism as a whole (in that it could exhaust the supply of labor-power available), but the working class fights back against exploitation, and at times is able to force limits to the length of the working day. What happens, then, when political legislation limits the working day to, say, eight hours? This is obviously a limit to capitalist accumulation. For capital, however, “every limit appears as a barrier to be overcome”. Relative surplus value is capital’s strategy for overcoming this limit.
