According to the 2013 survey by Japanese Nursing Association (JNA), the turnover rate of full-time nursing personnel who work at hospitals stands at 11.0%, without substantial increase or decrease over the past four years. This figure includes the turnover rate of newly graduated nursing personnel at 7.5%.While the number of nursing personnel in the workforce is increasing in Japan, many of them are leaving their jobs and practice. The underlying cause for this phenomenon is the demanding work environment that makes it difficult for nursing personnel to continue working. While the most common reasons for nursing personnel to leave their jobs are “marriage, childbirth and/or childrearing”, factors in workplace environment are also significant, including the irregular shift work, long work hours, burden of night shift, heavy responsibilities, and poor treatment.
