What is a common consequence of inadequate ventilation in offices?

Inadequate ventilation in offices can lead to a buildup of indoor air pollutants and insufficient fresh air circulation. This environment often results in various health issues for employees, including headaches, fatigue, and respiratory problems. Over time, these health issues can contribute to increased absenteeism, as employees may need to take time off work to recover from conditions caused by poor air quality. Ensuring proper ventilation is essential for maintaining a healthy workplace, which in turn supports employee well-being and productivity.

The other options indicate benefits that are unlikely to result from inadequate ventilation, as poor air quality is generally associated with negative health outcomes rather than improvements or enhanced productivity.
