Work per unit time is power. It can be thought of as rate of doing work.
Power is the rate at which work is done - i.e., at which energy is transferred. If you do work at a constant rate, then power doesn't change over time.
The term that represents the rate at which work is done is the watt. It is defined as 1 joule per second.

Power = energy / time"Energy" refers to transfer of energy, and it may specifically refer to work (which is the transfer of mechanical energy).
"Power" is the rate of work, or of energy transfer.
