I mean, I'm sure you're right. I just want to highlight that it's actually oppressive bullshit perpetrated by the rich, not "a funny quirk of a foreign culture". Of course when you try to avoid the notice, it won't work.
Of course we both agree that company straight up refusing to let you go is oppressive and scummy.
This is fine. What's not fine is not being able to determine when that notice period starts, or if it's allowed to start at all. This is the context of this thread.
Having a legal avenue for an employer to never allow an employee to quit is incredibly dystopian. Some might say analogous to slavery.
