On 27 Sep 2026 the Department of Labour Protection and Welfare issued a request (not a binding rule) after flood warnings for Bangkok and central, eastern and southern Thailand, with impacts expected until 29 Sep. Key asks: treat late arrival or absence caused by flooded homes or blocked travel as not a leave day or a disciplinary offence; prepare an emergency plan; check electrics, machinery and buildings for hazards; have the welfare committee support affected staff; and resolve issues in good faith with staff and unions. For a small business, decide now how you will record flood-related absences and check your premises before the rains return.
