From my understanding, the work function relates the photon's total energy, the required amount of threshold energy, and the kinetic energy. Essentially, it states that some of the photon's total energy is first used up to meet the threshold energy. Whatever is left over from that is energy that is put toward's the electron's kinetic energy. Thus, the sum of the electron's kinetic energy and the threshold energy equal to the photon's total energy.
I like to look at it according to the words "work" and "threshold." The work of the function is what is being done, or the action. The threshold is the point that must be reached. They are often synonymous because once the threshold energy is met the work function is performing.
