A lack of interest in the job suggests that the individual may not feel motivated or engaged, which can lead to a disregard for attendance. Personal or health issues are also significant factors; they may create circumstances that make it difficult for an individual to maintain regular attendance. Similarly, poor time management skills can contribute to tardiness if a crew member struggles to plan and allocate their time effectively.
