Jill Tucker, RN says:

“Low pay and physically demanding work are prime contributors to the shortage of health care workers in nursing homes. In addition, a more advanced level of care is required as patients with complex issues, who were formerly admitted to hospitals, are now placed in nursing homes. All of this leads to an incredibly high turnover rate for workers who care for the elderly and disabled. If nurses aides were compensated in any manner like athletes, firefighters and workers in manufacturing, (occupations as prone to injury as health care workers) the void in skilled direct-care nurses would fill very quickly.”
