The aim of the present study was (1) to examine the present state of communication among staff members of facilities covered by long-term care insurance (nursing-care service providers), (2) to elucidate the relationship between the work environment and communication among provider staff members, and (3) to investigate a method for improving the work environment in order to facilitate smooth communication among staff members while considering the education and training of provider care personnel. The present study administered a questionnaire to 1,806 providers; 915 valid responses were obtained. Approximately 90% of provider staff members, regarded communication as “rather good” or “good.” For providers with good communication, the ability considered most important when employing the staff was related to sympathy with business goals. The ability level required by providers was related to assisting executives and providing business management advice. One approach for work improvement was related to having sufficient authority or autonomy and specified roles and responsibilities. An approach for personnel development was related to substantial education and training immediately after employment. A prominent method for preventing early staff retirement (to promote settlement) was related to appropriate evaluation of a person’s skills and performance, with evaluation results being reflected in the person’s position and compensation.
