Working time satisfaction in aging nurses

Satisfaction with working time could represent an index of good balance between work and life and predict satisfactory work ability and endurance of aged workers. This study is aimed at checking whether elderly nurses who were satisfied with working hours had a better work ability index than those unsatisfied, and finding which factors were related to satisfaction of working time with reference to general “well being” and/or “private life”. The study sample consisted of 3,174 female nurses recruited in six European countries within the Nurses’ Early Exit Study. All were rotating shiftworkers (nights included) and 12.95 % were over 45 years of age. A composite questionnaire, including demands at work and in private life, working conditions, individual resources and alternatives to nursing profession, was administered to the participants at baseline and 1 yr later (Time 1). Work ability index (WAI) at time 1 was used as outcome, whereas age groups and satisfaction of working time at baseline were used as predictors, after adjusting for family status and number of children < 7yrs of age. Also “satisfaction with working time” at Time 1 was used as outcome, whereas working hours, job demand, leisure time, influence on planning rotas, family status, number of children, work/family conflicts, sleep at Time 0 were included as potential determinants. Conditional Random Forest analysis was used to evaluate high, moderate or weak importance of these determinants. Nurses satisfied with working time at time 0 showed a higher WAI (time1) than those unsatisfied in all age groups, also over 50. Less work/family conflicts and better quality and quantity sleep turned out to be the best predictors of satisfaction with working time. Consistently, the importance of the other predictors differs when the outcome is “satisfaction with working time” related to general well-being rather than to private life.
