How Japanese black companies oppress workers (2014)

Interestingly, this is actually possible under Japanese law/legal precedent. If an employee, for example, decides to put in notice and then half-ass their job until their departure date, a company could actually sue the employee and win.

Other Japan-labor-law fun fact: if you are a contract worker, it is literally illegal for you to quit prior to your contract expiry date. Hope you like that job you signed onto!

Obligatory disclaimer: IANAL

Having seen the perverse incentives this creates and the various ways in which it can be abused, I have come to the conclusion that the American “at-will” employment model is actually a good thing and benefits workers. No one should discount the value of having the power to tell your employer to fuck off at a moment’s notice with no practical repercussions. No one should be required to stay in an abusive relationship a moment longer than they wish to.

I don’t know in which countries you worked but I didn’t have any problems getting out of a contract.

COBRA costs you exactly how much you + your employer were paying for that insurance.

It's expensive because your employer's share of insurance was a significant part of your compensation (And because US healthcare costs are pants-on-head insane.) I'll point out that it's generally quite expensive to, like, stop getting paid.

Practically, post-ACA, health insurance in the US is about as tied to employment as having a roof over your head and food on your table is. If you don't have employment, or money, you're going to be in trouble - but that's the case with everything you need to live, not just healthcare.
