I'd almost agree with you diamondblue, but...
then problems will be few
I'm up to forty staff now, and I am NEVER short of problems. If there were no problems, they wouldn't need any managers. This reminds me of one office that kept track of customer inquiries under a column marked, "interruptions". People aren't interruptions to our business, they ARE our business! In the same sense, if I hated dealing with problems, I probably shouldn't be a manager.
On the other hand, I assiduously try and keep the numbers down. I train and groom my supervisors. I keep them healthy and happy. They take care of the routine problems, so I only have to deal with the biggies.
