Marginal product of labor is the change in total output as a result of a unit change in labor (variable factor) input.
Symbolically, the marginal product of labor can be written as:

From the graph, initially with low levels of employment of labor, marginal product rises with increase in labor employment but up-to point A when the second unit of labor is employed. From point A, further employment of labor will result in decreasing marginal product. Point A is the point of diminishing marginal returns. Initially there was increasing returns due to the benefits of specialization and division of labor but later, labor has less of the fixed factor to work with and starts interfering with each other.
