If this is known as a common business practice of this company why do any good employees stay? If the employee has enough value take it to somewhere else. I always keep my eye's open for a better opportunity for me and my family. My loyalty is to my family. My employer pays me for the work I perform and value I bring to them. They need something done and I do it because they pay me to do it. When they no longer need it or think they would be better off with someone else they will stop paying me and I will stop doing it.
