Ventajas
The pay is one of the highest, if not the highest, for teaching English at a language institute in Chile. If you have full time availability, they offer you more than enough work. There were also opportunities to do extra teaching projects on weekends to earn more.
Desventajas
The support system among teachers was not strong at all. Some of the teachers were willing to collaborate and become better teachers, but many were too prone to complaining about the institutes and eClass instead of channeling that energy into better themselves as professionals. Many teachers were just teaching because it was the only job they could easily find in Santiago as a native English speaker.
