Minpunten
The management is out to squeeze every dollar out of both the teaching staff and the parents. Teachers are given a huge workload and are often at the mercy of the team that does the class scheduling who are generally unempathetic and would take advantage of you if you are generally a cooperative and helpful colleague. You will realise that there is a lot of injustice. If you are a responsible employee, you will have to take over the slack from other teaching colleagues who take frequent and strategic MCs. After TLL was bought over by a private equity in 2014/2015, everything went downhill. Good teachers have left because of the culture change and you get a lot of junior teachers who are inexperienced and overworked. While it may pay slightly better than the average chains in this industry, the workload negates any additional perks you get.
