Pros
You have books provided, and administrative tasks are generally taken care of for you.
Cons
There is a significant lack of organisation. The academy is split into franchises so the franchises simply do what they want, despite the fact you are interviewed at the brand HQ. Your employer's often treat you like dirt. You are expected to fit your planning into your home life and take home any work you need to complete. Weekends are often taken away from you at late notice so you can run workshops/mock exams, or so some training can be provided. We once went 5 weeks without a weekend because of all of these. Pay is often less than the agreed total in your contract but if you complain about anything the employer will just terminate the contract so it's best to keep quiet and salary is generally paid off the books anyway so there is little to no evidence of this. You may also end up earning less than your colleagues at other academies within the franchise because your boss pays you what they like. Often you are not allowed to even copy resources and if there is a complaint made against you the bosses will always take the side of the parent/student and not the employee. You only have temporary contracts no matter how long you are around for and unfortunately, when the contract expires, there is every chance you may check back in the summer to find them hiring someone else in your job!
