Pros
Managment and CEO seemed very nice. This is an okay starting place for a teacher looking to gain experience but frustrating for one who may want to expand the lesson plan or is able to see areas of improvement in the supplementary material. This can be a benefit for first-time teachers. Coworkers are often supportive and we worked together to resolve any issues. While this depends on your branch, I've generally heard good things regarding employee relationships within the branches. Students were able to compete amongst each other by reading or completing book reports. The top students won prizes! Get a head start and make sure it is communicated in both English and Korean (for lower-level students) as many students may need the encouragement of prizes to do book reports and read. Holiday parties were often held and students seemed to enjoy these quite a lot. Teachers were given free range in planning. This may be seen as a con as this meant management was largely hands-off. Managment was supportive of lesson activities in class (however there was not always a lot of time to implement it). This was still a positive as many students struggle with comprehension and activities allowed for students to learn more material in class. Syllabi were partially completed (although needed altering to fit your branches needs). This was often time-consuming but you very rarely started from scratch.
Cons
There are some fundamental issues with the material teachers are given. As another poster said, it is very rigid but also very unorganized. The supplementary material is rather weak and there is not enough time given in the schedule to allow teachers to provide in-depth explanations. It was often a struggle to cover all the material assigned (example: Daily Quiz, activity (pref.), vocab test, review, 2 ~5 pages of the workbook, 1 ~2 books of reading in 25 ~45 min times frame). You don't have enough freedom when creating the syllabi. There are some areas of weakness that you have to incorporate because it's part of the franchised method of teaching. Management did not seem to have much guidance from the corporate office. This usually meant decisions were not communicated well or the franchised method of teaching was not well understood by managers. This allows staff to gain new skills (management, creativity, etc.), but often at the cost of receiving vital guidance to properly hone them. Training was non-existent and the staff was heavily watched through CCTV and sit-in observations. You were expected to be free of any mistakes. There was very little forgiveness for newbie mistakes and the natural learning curve for a new job. Teachers were nitpicked frequently (even if the classes were successful). It was quite nerve-wracking. Many students were bored with the assigned subject matter; I believe this was because lower-level classes used very basic, repetitive books (Pre-K & K level) for students who are in elementary age-range. It will be up to you (and your additional lesson activities) to make the material interesting and you might have to sacrifice other vital parts of your lesson to do so. The placement tests did not account for gaps in writing vs. speaking vs. comprehension, which often caused additional problems for students when conducting classes. Most teachers were overworked. There were not enough hours in the day to plan and prepare for classes within the allotted work hours.
