What is the change of output from adding one more worker called?

The change in output from adding one more worker is called marginal output. This works the same as marginal cost and marginal revenue. It is a measure of the effect that one more unit would have.

In theory, if adding one more worker increases output you could continue to add workers. If there comes a time when adding a new worker hurts productivity and output, you would NOT add the person.
