Taiwanese staff can be disrespectful and ruin your teaching experience

Are you a reasonably clean cut, complacent, semi-decent looking Caucasian male in your late 20s to early 30s? Congratulations, you are Hess material. You will likely encounter few problems while working with the Taiwanese staff at your buxiban. I would recommend this company to you solely on the basis of lack of teaching experience and few contacts in Taiwan. Keep in mind the possibility of 6 day work weeks, and being your branches go-to man for underpaid extracurricular work.

Now, if you don't belong to this minority, you may run into some issues. If the staff at your buxiban decide for some reason that they don't like who you are on the basis of your appearance, your personality, your ethnicity, your teaching style, etc, then you may have a difficult time. Poor relationships with the staff can be extremely stressful and make working with Hess a nightmare. This is of course subjective, and each branch is different, but micromanagement and internal hostility seem to be a recurring theme in many Hess buxibans.
Head office is aware of these issues, but unfortunately can do very little to change things.

If you are lucky enough to have a good experience with Hess, then you are of the minority. Life in Taiwan is of course what you make of it, but having an enjoyable job will make all the difference.
There are other cram schools which pay a higher starting wage, and give less extra admin work. Don't settle for Hess.
