I wish there was some law requiring surveying companies to fully disclose their method of contact and compensation. I can absolutely see an employee looking to leave their job being more receptive to taking a survey. Those happy with their jobs are not as likely to respond to third-party entities like "Hospital IQ" contacting them. Maybe the survey company masked this survey as a "pre-screen" to finding new jobs! We will never know. The process of recruiting survey participants has GREAT implications on the results.
