Another name for false productivity

Another name for false productivity is SPINNING YOUR WHEELS.

False productivity can be described as someone who looks productive but is not. 

Productivity is defined as a measure of efficiency of a person, machine, factory system, converting inputs into useful outputs.

False productivity is producing outputs that are not useful nor efficient.

An example of this scenario is: 
You are very busy doing a lot of stuff the whole day. You seem productive. But at the end of the day, you realized that everything who have done for the day is not important and does not complete any task. You just wasted a valuable amount of time doing things that are not worth your time. Thus, you are merely spinning your wheel without going anywhere.
