How can illness affect an employee's work performance?

Illness can significantly impact an employee's work performance by introducing symptoms such as headaches, fatigue, and other physical or mental challenges. These symptoms can diminish an individual's concentration, reduce their ability to complete tasks efficiently, and lead to absenteeism or decreased engagement at work. When employees experience pain or discomfort, their overall productivity tends to decline, making it difficult for them to perform at their best. Understanding this aspect of work performance is crucial, as it highlights the need for supportive workplace policies that recognize the impacts of health on productivity.
