The commonest form of slavery was "survival slavery" wherein one party is desperate and willing to exchange thier freedom for being ensured the basic provisions of life. This was exceptionally common back in the day, with there being the obligation to not leave, and is not really like a job though many of today would confuse it as such because they can't comprehend the concept that getting room and board is not the same as getting paid, especially when that's with the ever present threat of being kicked to the curb or beaten depending on the culture. And in a world where every apple matters, it's not exactly a simple thing to take on an extra mouth, particularly at first when they're usually weak and unable to do much, thus why the enslaved is made to work so hard. This naturally progresses into abusive systemic norms which weve seen develop in so many societies in history, but really it appears to me they almost all seem to start in a "survival slavery" format.
