Final answer:
Attendance as a measure of performance is problematic as it doesn't account for productivity, could contain irregularities, and might lead to statistical discrimination.
Step-by-step explanation:
Using attendance as a measure of performance might be problematic because attendance is a measure that while easy to quantify, does not account for the quality of performance or the actual work accomplished. First and foremost, attendance records may not reflect the capacity in which the employee is actively engaged in their duties during their time at work.
Plus, it doesn’t consider the output of work done outside regular hours, such as homework or long-term projects, which might be a significant part of an employee's responsibilities. Secondly, there could be irregularities in the attendance records due to errors, or employees might be present but not productive (presenteeism).
