There are only two things that can save Nova now, neither of which appears likely: students inexplicably return to Nova in droves or an angel investor bails out or buys them. Given the uncertainty surrounding Nova's future, it's time to review how one goes about collecting unemployment insurance in the event that Nova goes bankrupt.
If you currently work for Nova, you have two choices: you can quit now, or you can wait for Nova to go bankrupt.
The good: If you quit now and manage to find another job, you're safe. You're free of Nova.
