Wow John.....
You are certainly entitled to your opnion and perspective on things, but let me pass a little factual info your way from someone ACTUALLY IN THE FIELD.
1) A course I know, in a "brilliant" move by upper managment, decided to let go of their "over-salaried" super and hire a mechanic to take his place. The mechanic had been working in the field for years, had plenty of hands-on experience and was an excellent worker under the previous superintendent. Why not? Well.....needless to say he was fired within two years, only after driving the condition of the course into the ground, causing thousands of dollars worth of neglected, "deferred" maintenance issues, not to mention TENS of thousands in lost revenue do to the bad press and PR the course got for sliding so far down hill. This was over 5 years ago and they're still feeling it financially.
2) My current assistant is a VERY adept, intelligent Mexican young man who has alot of potential to be a superintendent someday.........should he want it. But he doesn't. Can you even think of why? One......upper management might want to know a LITTLE more about his legality before they put him in charge of an over-half-a-million budget. Do you think "cheap labor" is cheap just because they're Mexican? My assistant informs me that there's almost no way a Mexican "with papers" would work on a golf course, because they could make twice as much in a number of other industries. Right now, my assistant gets paid well, to be second in command, to do as he pleases more or less, to go home after 8 hours and not feel any responsibility with his job on the line should the slightest thing go wrong. If a disease ravages the greens to the point of no return, I go......not him. He likes that security. He's got a plush job by many people's standards and he likes it here, and I like him there with me as well. I couldn't do it without him. Plus.....why become a superintendent when he can make twice as much running a landscaping company? Which is precisely what he's working toward......between his pay at the course and his side jobs, he makes more than me. Almost makes me want to think about landscaping..........
In conclusion, your "idea" has no real basis in this discussion as a cost savings plan. Feel free to try it out......but please put only your own club at risk, not mine.
