You'd be super wrong there, at least in my case: I'm late all the time, not only do I still have my job, I get great reviews and token raises every time I'm up for review. If I left, they'd be in trouble, they definitely won't fire me. I don't bust my ass and they understand I won't be taking calls outside of designated hours, doing anything heroic, etc. but I am still very valuable to my employer.

I joked about having a job interview once during a meeting with leadership and it was one of the most awkward silences I'd ever heard until I told them I was just kidding: They thought I was serious and their terror was palpable. My manager once told me I'd have to commit multiple crimes to get fired when I made a joke about getting fired because there was an end of day meeting on a Friday.

I stay because it's a chill job and I like most of the people I work with even though the pay isn't amazing, but I could probably go somewhere else and make at least 30-50% more, though at the possible cost of more stress and less job security. My commute is pretty great too, 2 miles away and sometimes I even walk to work.
