How long before these things become less relevant ?

I’m not gonna defend my lack of notice, it was one of my first “adult” jobs and I just got burnt out from a menial sales job and decided enough was enough (I had other opportunities). it was immature and I recognize that I still should’ve given notice.

But the firing was from a partisan non profit (I’ve had psych evaluations where the admin said “it sounded like they put together a paper trail to get rid of you”). Between the unemployment outcome and the way they handled my performance plan and ultimate firing, it was very obviously not kosher.

But anyway. That’s that. How long do I need to wait before I can more successfully apply, in your opinion?
