Interac is an ALT dispatch company in Japan. They are captains of industry of the world, who rightly treat gaijin teachers like the scumbags they are

Yeah and they have been doing it for many years. In the past, interac would do shit like give you 29.5 hours of work per week (would have had to give benefits from 30) and consider EVERY single period that is not a class as free time. Imagine, you are going to school, have 1st, 3rd and 5th period, and while you are still at school during 2nd and 4th, it would be considered free time and not count towards the 29.5 hours. That is the kind of scummy rats that they are. And if the laws change, they will try again to squeeze as much out of the teachers as they can for as little as they can possibly give them. They are evil in the most pure sense of the word. So, without trying to throw shade on ANY person working under such conditions, try to avoid those parasites as much as you possibly can, and gtfo as fast as you can if you have no other choice at the moment.
