Maintaining and promoting teachers’ work ability is essential for increasing productivity and preventing early exit from the teaching profession. This study aimed to identify the predictors of work ability among upper-secondary school teachers and examine the mediating role of burnout. A large and diverse group of Czech upper-secondary school teachers was surveyed to address this goal. The sample comprised 531 upper-secondary school teachers (50.0 ± 9.94 years, 19.9 ± 10.62 in the teaching profession, 57.6% females). Relatively greater empirical support was found for the effects of burnout, sense of coherence, work–life balance, and perceived relationships in the school environment on work ability than for the impact of age, homeroom teacher duties, workload, and caring for elderly relatives. Furthermore, burnout served as an important mediator of the relationship between sense of coherence and work ability. Teachers with a higher sense of coherence are thus better able to cope with adverse work circumstances and identify and mobilize internal and external resources to prevent professional exhaustion and the subsequent decline in work ability. The study can guide interventions on the work ability of teachers.
Background: An aging workforce is a global phenomenon with significant implications for European countries. Interventions facilitating the active performance of work until retirement age have consequently been developed. A new concept of work ability, which comprehensively describes the way to achieve a better correspondence between aging and work, has been created in Finland as of the end of the twentieth century. It also includes an objective measurement of work ability based on the index of work ability. The use of methods of objectification of work ability upon determination of the WAI index is still at an early stage in the Czech Republic. Objectives: To determine the WAI values for different demographic groups of the Czech population older than 50 years of age, the relationship between working abilities with demographic and anthropometric characteristics and diseases of an individual. Methods: The research tool is a questionnaire to measure the Work Ability Index (WAI), translated into the Czech language. The survey involved 361 respondents from six companies and organizations, including a group of 60 unemployed persons registered at the Labor Office. The data collection took place from September 2014 to February 2015. The software Statistica Cz 12 was used for data evaluation. Results: The average value of WAI in the case of the sample was 39.4 ± 7.03 and attained higher than the Dutch reference values. The statistical tests showed that men achieve higher WAI than women, WAI decreases with a higher amount of BMI and the number of diseases diagnosed by a physician. A statistically significant relationship between WAI and the type of work performed was also found. Conclusions: This paper presents data and their assessment obtained by measuring work ability through the WAI index in the first 361 workers of six companies and organizations in the fields of banking, government, healthcare and industrial sectors. It also presents current knowledge concerning the objectification of work ability under real conditions for Czech employers through the method of determining the WAI index.
