Growing businesses create policy after policy to stop bad situations recurring. Imagine that instead of creating more rules, you just removed the people that were causing the problems? 

For example, if one team member continually claimed excess fuel allowance by driving the long way to client sites every single day.  When their manager found out, some sort of policy like: “fuel allowance only applies when the most direct practicable route to a client site exceeds XXkm and must be verified by a manager every week”  might be created.

What if, instead of creating another policy for everyone, you respectfully (& legally) parted company with that one problematic person? The result: you’d have less petty problems to deal with and all of your best people would be left alone to keep doing what they do best.  

Instead of policy-making for the minority and upsetting the majority, why not just eliminate the problem?
