How does uneven productivity impact the office, employee morale, and company's business?

Question

The question refers to an example if there were four employees that each had two assistants. Two of the employees usually have nothing to do because their assistants do all their work. The other two employees usually have to work over time, one of them have an assistant that works 15 hours and the other employee does not have an assistant. With that said, how does that affect impact, morale, and business? Also if you would be kind as to give a few ideas as how to fix this problem, that would be nice. I thank you.

Answer 1

Production is the basis of morale.

Fire the 2 employees who do nothing.

Re-Assign their assistants to the other employees so there is no overtime paid.
