people do not quit jobs, they quit managers and I personally would like to quit some coworkers.
Basically the manager says in public that I’m good and passionate about the job but privately she writes the opposite. She never talked to me about what I need to improve, if anything. And then has the gall to tell me to trust her if I want to open up to her. Two faced, not to trust.
I only found out when another manager read to me what she wrote about me.
I was never good at playing office politics. FWIW I don’t like the job, I do it because I need money and I’m good at it.
What’s the benefit of making them fire you over simply quitting after you’ve lined something better up?
Satisfaction at making your asshole boss do something that he/she clearly didn’t want to do. Satisfaction that you made it as awkward as possible for them. You can also play the game of threatening to take them to an industrial tribunal for harassment. They might even give you a financial incentive to go peacefully. It worked for me on a couple of occasions and the bastards deserved it.
I’m sure it varies by state, but in the US, you cannot collect unemployment if you quit, but you can if you were fired (and the company doesn’t decide to fight your claim).
That’s at least one reason people do it.
