It depends on the number of members the teachers have on their rosters. The majority of my teachers teach a minimum of 10 to 14 members of Parliament.
We really have to be able to align the schedules of the members and the teachers. If a member wants more flexibility, as has happened many times in the past, we change things by assigning a teacher to him who is much more available.
However, certain members prefer set schedules, and others do not. We try to meet their needs.
