overwork 労働関係の英語

I learn English 3times a week from a Canadian tutor, and 2times from Filippino tutors on the internet.
In the Last Filippino tutor’s class, I heard about their overwork, but I couldn’t talk with them enough because of my English skills, so I asked a Canadian tutor about the English word for labour.

【These are new words】
・I wondered if there is not a Labour Bureau in the Philippines
・They inspect the company to see if they are in compliance with Labour
・All of the companies have to be in compliance with labour laws.
・They have to sleep divided into small pieces.
・they don't get a full night's rest.
・This school's owner is Japanese man. He wouldn't get away with it in Japan but the school is in the Philippines, so he overwork the English teachers

Inspectors = bureau staff
Inspect - verb
