Working at School

About one month has passed since I started to work for the current junior high school.
The job is more easygoing than the previous job in a junior high school because I am not belong to a certain homeroom.
If you belong to a certain homeroom, you need to be in the classroom all the time and to do a lot of tasks about the students.
However, unlike previous year, I don’t need to do that job, so I can focus on preparing lessons.
Also, there is an atmosphere in current school that we leave school right after the work hours.
I will leave the school at 4:30 p.m. right on time today.
