When you add a manager to a business, you add overhead. So the first effect of hiring someone to replace yourself as manager or supervisor - so you can work on your business instead of in it - is to take a real hit in profitability.
What if, instead of appointing someone new to manage your people, you appointed them to manage themselves? You could use the saving in overhead to invest in them instead, building a supporting framework, coaching, mentoring, training, and of course a fair share of the rewards.
When you want to expand to serve more customers or clients, you can simply add more people.
Those who’ve taken this approach have found the return on this kind of investment to be well worth it.
