Which of the following aspects is closely related to the rate of staff absenteeism?

Employee satisfaction is closely related to the rate of staff absenteeism because higher levels of satisfaction typically correlate with lower absenteeism rates. When employees feel valued, motivated, and content in their work environment, they are more likely to attend work regularly. Factors contributing to employee satisfaction include a positive workplace culture, effective management, opportunities for growth, and good working conditions. Satisfied employees are generally more committed and engaged, reducing the likelihood of them needing to take days off due to stress or dissatisfaction.

On the other hand, factors like production costs, market share growth, and customer engagement, while important for a business's overall performance, do not directly influence how frequently employees choose to attend work. High production costs may arise from absenteeism, but they do not necessarily cause it. Similarly, market share growth and customer engagement relate to external business performance metrics rather than the internal dynamics and morale of employees.
