Which of the following is NOT a personal problem that can affect employee performance?

Time management is centered around an employee's ability to prioritize tasks and manage their workload efficiently, which, while influential on performance, is a skill rather than a personal problem. It often involves organizational strategies and practices an individual can adopt to improve work habits.

In contrast, alcohol, illiteracy, and domestic issues are personal challenges that can have significant impacts on an individual’s performance in the workplace. Alcohol dependency can lead to absenteeism and diminished productivity, illiteracy can hinder effective communication and job competency, and domestic issues often create emotional distractions that can affect focus and efficiency. Thus, time management stands apart as a skill that can be developed and improved, rather than a personal problem.
