Low compensation, especially for non-natives.
Excessive unpaid training, constant updates of training materials, reviews of teachers, some halls with speaking all the same for years, they want constant improvements of teachers, when actually they don't have IT support to help students with their horrible technical issues during classes, login, chewing, eating, making noise and have inappropriate behavior. No progress for teachers, no chance to make any progress. Negative ratings, sometimes due to factors beyond the tutor's control, can adversely affect their earnings and schedule, Unfair rating is something that's happening over the years.
