My brother works as a labor and social security attorney.

He injured his arm in a workplace accident.

His efforts were like a mantis trying to stop a chariot, he couldn't achieve any results.

Thank you for your hard work until late.

Kinichiro is my best friend.

Workers of the world, unite, the time has come to show our strength.

Workers of all countries, unite, let's show our power.

He rubbed his hands together to get warm.

He tampered with my plan.

He was dragging the heavy luggage.
