BACKGROUND: While absenteeism refers to not attending work, presenteeism is defined as not being present at work. These two conditions, which negatively affect employee health, can be indicators of work efficiency, work peace, work safety and work engagement. OBJECTIVE: Several factors were evaluated in this study concerning absenteeism and presenteeism among factory workers. METHODS: This cross-sectional study was conducted among workers in a factory operating in a heavy industry in southern Turkey in 2021. A survey consisting of 57 questions was applied to 152 factory workers by face-to-face interview method. The participants’ behaviour over the last month was evaluated regarding absenteeism and presenteeism. RESULTS: It was reported that 24 (15.8%) of all employees were absent from work in the last month (absenteeism), excluding holidays and sick leave, and that 20 (13.2%) employees engaged in presenteeism, working when they should not have been at the workplace. There was a high absenteeism rate among employees who had an acute illness and were dissatisfied with their jobs. Several factors have been associated with presenteeism, including poor economic conditions, family health problems, previous unemployment, working overtime, job dissatisfaction, poor relationships with colleagues and difficulty finding a replacement, acute illness, sleep problems and fatigue. CONCLUSIONS: To increase the productivity and commitment of employees, it may be useful to identify the reasons for absenteeism and present behaviours, to facilitate effective interpersonal communication skills by examining the organisational climate of employees, and to regulate workload based on a comprehensive assessment of the health status of employees.
