what is the difference between sensor & thermometer?
Business is about making as much money as possible. The way you make the most money is by having the best staff, amongst other things. If there are two people vying for the same job, at the same price, and one has the obvious upperhand, then you must choose the employee that best suits your company. It might make you feel bad, but if the guy was good enough to hire, there will be other oppurtunities elsewhere. However, you can't let your competition get the experienced guy because your feelings got in the way of making a rational business decision. Remember, you aren't throwing Guy 1 onto the streets, he will do well elsewhere, so don't feel bad about firing him. It's strictly business.
