what does a native speaker say when he wanted to leave his work? [closed]

If someone, who is a medical doctor says that he's leaving his current company, I mean the hospital that he works for, is that something that a native speaker would say? I'm leaving my hospital?

What else to say also would be possible?

I quit my hospital? I will knock off the hospital that I work?

Thanks.

I wouldn't say, "I quit my hospital?" I would say 'I quit my job', 'I'm leaving my job'. To be more descriptive I would say, 'I quit my job at the hospital' or 'I quit my hospital job'. Leaving could replace quit in these examples as well.

To me saying "knock off" sounds like one is leaving for the day. I'll knock off for the night.

2. verb, slang To stop doing whatever one is doing. Often used as an imperative. In this usage, a noun or pronoun can be used between "knock" and "off," especially in the common phrase "knock it off." Knock it off, you two! I don't want to see any more fighting. I'm going to go tell those kids to knock off all the shouting.
