I've said it before and I'll say it again - everyone coming to Thailand should work at a language center for a while.
This holds especially true if you are not an experienced teacher or are new to Thailand.
You can work as little or as much as you want to.
They are well resourced.
You'll never have to buy another Bangkok Post again!
Free coffee and banana cake!
Air conditioned classes.
Always easy to get to, with buses and taxis right outside the door.
Valuable on the job, paid training and learning.
The money is rubbish compared to a salaried job.
If you don't work, you don't get paid.
The atmosphere is cliquey and you'll often get the Thai 'Flavor of the Month' syndrome to deal with.
Students can easily say that they want to change teacher if they don't like you for any reason.
It's just depressing working at a language center after a while.
But as an apprenticeship, it can't be beaten.
Do it for six months, learn everything you can, steal all their resources onto your laptop and run... run as fast as you can!
