1- I work with people, but I work for a company. This is an extremely important point to clarify. I don't work for people, even if the company is represented by people.

2- Being kind is great. Love it. Do it all the time.

Here's where the problem comes in with your hypothetical, and my baseline assumption: "If it doesn't cost you anything and it will make the life of your employer (or a complete stranger for that matter), I suggest you go ahead and do it."

This Is A Bold Assumption You Are Making

Quitting a job isn't easy. There's going to be guilt. There's going to be stress. And, based on the title of the article, you have a bad boss. What form this "bad" takes can be a million different things, but it's safe to say that having a shitty conversation with a bad boss is going to cost me "something" (even if it's just my time).

Respect is earned. That's my starting point. If I no-call no-show, it's because I don't respect you enough to care about the damage it will cause the company. I'm generally not a blatant asshole, so something probably happened in order for me to feel this way.

If we want to go down this rabbit hole, it gets to crazy levels of ethical questions (is it "good" to quit a job you're great at just because you don't like it, since that will cause problems for the person who has to train your replacement and they likely won't do it as well as you, potentially costing the company money in losses, etc .)

My summary is this: If I'm ghosting you, it's probably you're fault. You should take this time to reflect on why you sucked so bad that I wouldn't even have the decency to call you to let you know I quit. YMMV.
