The school asked for too much flexibility on the part of the teachers. After the schedule started filling up with private, or one on one lessons, the management would feel free to move those lessons around if the student requested a temporary change. This meant the teacher could not plan his or her personal time very well. Larger classes with set schedules went to teachers with more seniority. Staff would sometimes have difficult words amongst themselves about various communication needs or misunderstandings with foreign teachers because their English skills were not as good as needed.
