An HR columnist argues attendance bonuses ("เบี้ยขยัน") are often used to top up low base pay and to keep them out of the wage base for overtime, severance and social security. He warns that if the bonus is not truly an incentive for extra output, it can be reclassified as wages and included in those calculations anyway. Owners paying attendance allowances should review whether the payment is tied to attendance rules, and consider linking extra pay to output above standard instead. This is an opinion column, not a legal ruling.
