This would fall under the five yaer rule. What would be the split in the wages in five years. And which one would have more loyalty to you. I would rather have a long term than a short shot in the pants with a slight twist at the end. Machinest are in demand at the moument what about next year? In a 4 person shop it would be a big percentage dif at letting one go vrs a 200 person shop (ie 1/4 vrs 1/200) one would be aperson and the other a small number.
just my 5 cents worth.
