Pros
I don't want to paint an entirely negative picture. There is a great conviviality among the employees and the foreign teachers are all very friendly and supportive. Unlike most academies in Korea, WILS has some advantages. There are no CCTV cameras in the classroom, meaning the teachers aren't always being watched. Teachers here have a fair bit amount of freedom to run their lessons as they want without being held under the microscope. The kids are really friendly and the parents are, for the most part, quite supportive as well. Apartments provided are all quite nice (though some lack wifi). Despite some frustrations with the job, I overall had a good time in Korea and an unforgettable experience, though there are several aspects of the job which caused many frustrations...
Cons
Working at WILS can be very frustrating, especially for foreign teachers. First off, there is near-no organization or forward planning. Schedules are messy and disorganized and subject to change at the last minute. We would often receive our teaching timetable for the next day via Facebook message late the night before. Though our schedules didn't change on a daily basis, we would often be given new classes at the last minute without prior notice. Things are always moving around and are hard to keep track of, and even the classroom design keeps changing because no one can make up their mind. Management is extremely disorganized and nothing gets communicated properly. Teachers often receive messages meant for them at the last minute, or sometimes not at all, and then get blamed for "errors" which was clearly not their fault. At the same time, management makes many impulsive decisions at the last minute which directly affect students and teachers, and often make no sense. Dealing with management or voicing any concerns/displeasure often gets disregarded or ignored, and a fair bit of insistence is necessary. Teachers who do voice their concerns are immediately disliked by management, who like to pick favourites. It is important to remember that WILS, despite being a language academy, is a business before it is a school. As such, the decisions management makes are motivated more by financial opportunity rather than what is best for students and teachers. Given this, many decisions regarding "education" make little sense and are of little benefit to the actual students. Teacher well-being is also not prioritized, as teachers and staff are often treated poorly (example: being heavily pressured and sometimes required to come in on a scheduled day off - which there aren't many of to start off with). Teachers are given hardly any positive recognition for all their hard work and are instead blamed or criticized over the smallest details (that they may not even be responsible for!). To note: salaries at WILS are generally lower than what other academies pay, and many teachers earn hourly wages as opposed to earning a fixed monthly salary. The hourly teachers, in particular, can be sometimes required to work 12-hour days, and are NEVER remunerated for any prep work... only paid for hours spent in a classroom with students. Payments are often made on time, but can sometimes be late (as happened to me on three occasions), and receiving your severance payment at the end of your contract can take a few months. Overall: Working at WILS is not without its fair share of frustrations. The management's extreme lack of organization and less than acceptable treatment of teachers definitely does this business a disservice. Class with the students was fun, however, and there was a great atmosphere among the teachers. Would I recommend working at WILS? Not really. Things actually got worse over the period of time during which I was there, not better, and dealing with management is nearly impossible, so I would advise to pick a place that's more willing to dedicate more time ensuring that both students and teachers can smoothly go about their job.
