Does the "Equal Work Equal Pay" legislation account for productivity differences?

What if a man and woman have the identical job title, duties, education, and tenure but she is willing to work longer hours, take less time off, and is simply more productive than him?

Will the employer be forced to pay them the same amount?

Should they be paid the same simply because the do the "exact same job" if there are big differences in productivity?

What a great way to motivate people to do just enough to not get fired since they will all get the same pay no matter how little they do. What will they think of next?
