A lot of companies do not keep strict attendance records for their employees, and of course many people work overtime at home at night or at the weekend. As a result, the figures often do not accurately reflect actual working hours.
爭議在於，依勞基法規定，上述標準已經違法，雇主怎麼可能承認；其次，許多工作並沒有打卡規定，更多人利用晚上及假日在家加班，只計算正式工時，無法反映勞動實況。
