The bolded part is industry dependent. You can probably count on it in a service intensive industry, but you may see an increase in productivity, and a smaller employee count, in more manufacturing or production based industries.
But an increase in productivity would push Long Run Aggregate Supply to the right, thus lengthening the amount of time for the business cycle to reach full production. So you end up with the same effect. Remember, we're talking economy-wide here.
The other comment is the time factor between the change in policy, or the change in the macro level factors, and the implementation of the new paradigm. The length of that transition time is not trivial, in either the political nor the economic sense.
But no amount of force can make it happen any faster. The only thing it can do is make the problem worse.
