Presenteeism, a significant yet often overlooked problem in modern business, refers to an employee being at work despite being physically or mentally unable to perform their duties. Unlike the traditional concept of absence, it doesn't refer to simply not going to work, but rather being present but not mentally present. This situation is often rooted in psychosocial factors such as job insecurity, heavy workloads, a sense of loyalty, or the perception of illness as a sign of weakness. While presenteeism may seem to prevent disruptions in the short term, this is a completely wrong approach. In the long term, presenteeism has devastating negative effects on both the individual and the organization. Individuals experience chronic fatigue, burnout syndrome, and a deepening of existing health problems, while organizations face increased rates of erroneous decisions, workplace accidents, low morale, and indirect costs that far outweigh the direct costs of absence. Research shows that the loss of productivity leads to higher economic damage than direct absenteeism. Managers showing sensitivity to employees' health and promoting a culture of rest when sick is the first step in combating this problem. Furthermore, adopting flexible working models, establishing a psychologically safe environment, and evaluating performance criteria based not only on "time spent in the office" but also on tangible outcomes are crucial for breaking the presenteeism cycle. Ultimately, presenteeism is a human resources management problem, and its solution lies in a corporate climate that prioritizes work-life balance.
