5 most common employee benefits for English teachers in Thailand
What kind of employee benefits are available to teachers in the country?
Every employee working in Thailand will get social security, and some employers will apply for it on your behalf. You must pay 5% of your monthly salary, up to a maximum of THB ฿750, which will be taken directly from your paycheck.
