It has to go both ways, though. At my last job, when I first talked to the CTO (my boss) about leaving, he asked me to think about it and talk again the next day. The next day he postponed the meeting. Then, at the day of the meeting, he was out of the office. It had been 5 days since the first talk so I chose to escalate the matter and, in an Arrested-Development-episode kind of situation, I learned that the CEO and the CTO decided to mysteriously leave for vacation because they felt burnout.
I'm curious what would have happened, had you also taken a sick vacation then.
BTW, generally, people are less likely to pull off shit like that if you motivate your resignation with some health/moving/whatever external factors. Just shift the focus way from "I don't want to work with you assholes" to "my wife got reassigned to %STATENAME%, so I guess I have to follow" or whatever sounds plausible and you're good to go.
My best quit excuse was that I had Crohn's disease. It let me step away immediately, because I didn't want to poop myself in the office.
I also offered to work from home for my final two weeks, to help them train my replacement, but it had to be from home, because of the pooping issue.
What's really nice is that I had a ton of options. I could even apply to have my job back, if I couldn't find remote work, in a few months if I had success with the treatment and felt more comfortable in an office environment.
