• It's OK but it's easier and quicker if I do it myself
• I don't have the money right now
Word will get around and you'll risk becoming an RTO employer which people avoid.
Result #2 Cry Wolf
Because you've knocked back help so many times, when you actually do need it due to illness, personal or financial circumstances; there'll be no one coming to your aid because you've burnt those bridges in the past.
Result #3 It's Always Them
When people see the same people doing the same roles for an extensive period of time, they know they have no chance of being involved until the person eventually hands over the baton, either by choice (rarely) or death.
This is also true in my church where I see the same people doing particular roles on special ceremony days eg Easter and no else is allowed to do them. Yet these people, who are getting on in years, some with difficulty in walking or carrying heavy items, persist in wanting to be on show rather than letting someone else have a go.
Is it any wonder our rates for volunteers willing to help out is at an all time low?
Result #4 I Don't Know What To Do
Unless processes and knowledge are written down, it will probably always be quicker and easier for you to do things yourself.
But this means you will never grow your RTO to the level you desire; and the people around you will more than likely leave rather than stay in an environment which doesn't allow them to improve their knowledge and skills.
Result #5 On Your Bottom Line
Even though I have parked the financial numbers, I'm sure you also know the impact saying No is having on your productivity and profitability. There's no point paying for staff if you don't give them the tools they need to do their jobs properly which includes letting go.
