Career Transition: Teaching vs. BPO
Analyze in your mind why you suddenly switched from teaching to a BPO firm. The job contents are totally different. Teaching is a noble profession. Was it money considerations or issues in the teaching job that made you change over? You have to take a hard look at the present job and see whether it will suit you after some years.
While teaching is a profession with totally different requirements and satisfaction levels, one must have an inclination towards the profession. Not everyone is cut out to be a good teacher, but they can shine in other professions. A teacher needs to be professionally knowledgeable and constantly updating their techniques of teaching, interaction with students, etc. Teachers have to be meticulous in their work—they should be sharp to point out spelling and grammar mistakes, which means they themselves need to maintain high standards when in class or dealing with students.
This career decision can only be taken by you based on your outlook. A teaching job will give mental satisfaction much beyond what a BPO job can give. It is basically your call.
