Imagine you run a mowing service with 4 employees. Suddenly 2 more people volunteer to mow yard for your company for free!
Is your reaction to fire two of the paid employees and keep mowing the same number of yards (with reduced payroll costs), or to expand the business to mow more yards?
Which of those responses feels more in line with a "strong and growing" business that is "continuing to support more customers" and has "improving profitability"?
It is a productivity multiplier at least for now.
