- Strict and unfair salary deduction and penalty system. This is one of the worst aspects about companies that implement that system. It killed my motivation and morale. It also causes a high turnover or losing skilled teachers.
- Second negative point is the poor work-life balance especially if you work full-time. It requires someone who's single and without commitments, just free to work and burn out. There's only a one hour break for 8 hours of sessions. This is also exhausting and causes fatigue the more sessions go on. No hobbies, no personal time, etc.
