I'm not going to collect tickets for an award ceremony I was nominated for, because I've decided I want to cut all ties with my former workplace.
Why do you want to cut ties with your former workplace?
I'm fed up with them for not appreciating my work.
Not being appreciated really sucks. Still, you were nominated for an award. Isn't that something that could help benefit your career?
I'm more successful than them anyways. I don't need that award.
Even still, it sounds like they are at least trying to do the right thing and give you an award. I think you should try and be grateful of that and accept it.
