Section 581
Statutory text (Thai original)
ถ้าระยะเวลาที่ได้ตกลงว่าจ้างกันนั้นสุดสิ้นลงแล้ว ลูกจ้างยังคงทำงานอยู่ต่อไปอีก และนายจ้างรู้ดังนั้นก็ไม่ทักท้วงไซร้ ท่านให้สันนิษฐานไว้ก่อนว่าคู่สัญญาเป็นอันได้ทำสัญญาจ้างกันใหม่โดยความอย่างเดียวกันกับสัญญาเดิม แต่คู่สัญญาฝ่ายใดฝ่ายหนึ่งอาจจะเลิกสัญญาเสียได้ด้วยการบอกกล่าวตามความในมาตราต่อไปนี้
Verbatim from the Royal Gazette / Office of the Council of State
English translation
