I heard there is a number that we can call to check to see if our hagwons are taking out the right amount of money for the pension and to make sure they are taking it out! Also, if you have an ARC card does that automatically mean you have health coverage? My friend works for a school that was saying they weren't going to register for the pension which I think means she will not have health coverage. If you have info or a number I can call to confirm this that would be great!
First of all, you've gotta keep every pay stub that your employer gives you. If they don't give you one, then demand it. Once you've worked for a few months, then you can start comparing deductions to make sure they're being honest. Always be organized and stay on top of anything related to money. Not only will it help you avoid any potential problems, but it keeps the school in check for future teachers as well.
Depending on nationality, your employer is forced to pay into your pension. The amount, of course, depends on your salary. You won't be able to call the pension office and get private information on the phone, but you can go there with your passport and ARC. Just take a look at the Pension Office website for location details.
You have insurance. Having your ARC doesn't give you health coverage automatically, but it does suggest that your school is officially sponsoring your visa which gives you government insurance. Paying into insurance isn't an option. As a tax-paying citizen, you have to pay into it. The pension has nothing to do with health insurance. Your friend needs to talk to the school and get their insurance card (it looks like a book). That should be easy enough. If they refuse then something is wrong and a call to the Labor Board should clear that up.
