It can be difficult to hire in this environment. I've had 3 employees quit less than 3 months into new full-time positions. My first inclination is to ask, "What are we doing wrong?" but the more I look around it seems like a common industry problem. Perhaps it's rational behavior - as the article highlights, companies now view people as disposable. There's loyalty to a manager, but not a company. (You always want a good reference)
