[Working in the US; is it ever acceptable to leave without a two week notice?]

If it's not specified in your contract, you may not have to notify in advance. It would be more of a courtesy to let your employer know. Personally, I usually tried to give a heads up, except in the case of a similarly toxic manager who gradually increased my responsibilities without trying to be argumentative  and believed I should do absolutely everything he said, meaning everything. Initially, my colleagues and I joked that he would soon ask us to wash his car, but then it stopped sounding like a joke. I stood up and left.

work is an integral part of our lives, each of us needs to know how to assert our boundaries. My choice is to study at https://edubirdie.com/examples/argumentative-essays/ to always have different options. Employers vary, and I want to be prepared.

[Do You Think Becoming Blind is a Fate Worse Than Death?]

For me - yes. I've noticed that many messages are reinforced with a photo in the messenger when someone asks something. And I want to respond in a similar way. Besides, video games, books. I can't imagine how to live without them.
