People often think that teacher has a very easy job. It is easy in some ways, and in others it is difficult. The easiest part about it is the spacious routine. There are not many teachers who, like businessmen and professional people, are on duty forty-eight or fifty weeks a year every year; and there are still few who teach from nine to five every (lay, five days a week. Most schools and colleges run for only nine months in the year alto gether, and there is seldom any necessity for a teacher to be on call every hour of the working day. Of course, there is a great deal to be done outside teaching hours. Some of it is routine -- preparing examinations, reading papers, interviewing pupils. Some of it is research and preparation. )3ut much of this kind of work can be done in one’s own time, at one sown home.
