In order to succeed in this highly competitive and culturally bustling city, English is a tool required in most fields, especially tourism, commerce and business, as many of the office buildings around the city centre are owned by multinational companies. Most of these companies hire freelance teachers of English for group classes, or private individual lessons, generally at lunchtime. The fee could range between 80 and 100 pesos an hour. These lessons might have to focus on skills such as fluency and public speaking for business meetings and presentations. I have taught in companies for almost 10 years, and it can get really laid-back, as the student is constantly on the phone, or being summoned by his manager; or if he is the manager, he may have to call off your lesson unexpectedly, and you may find yourself with some free time on your hands. It is of vital importance to agree on a cancellation policy beforehand with your students, as they may not want to pay for a lesson they have not taken, but if for example they have cancelled 2 hours before the lesson, you may charge for it anyway, as you have invested time in preparing it and that time is part of the fee.
