Could you tell which preposition: in or at it is correct and natural to use in the following sentences?

The thing is, I didn't like the working hours in/at my previous job, which is why I quit.

I have a lot on my plate in/at my job at the moment.

I would only use at my job in two contexts:

  1. Where it is referring to a way or quality of doing the job:

I'm not very good at my job.

He's very clever at his job.

They're methodical at their jobs.

  1. Where it is referring metonymically to the place where I work.

There's somebody at my job who keeps annoying me.

(This use is not very common - more often people say at work or at my office, or at the shop - but you hear it sometimes).

So in both your examples at my job is possible, in the second sense; but in my job is much more likely. In the first case, I'd say that of or for is more likely still.

  • Thank you for the great answer! I am confused though. Could you clear things up please? You said "in my job" is more likely. More likely in which case? For talking about working hours or workload. And how is "of" and "for" are relevent? Could you tell me what you mean by saying "of" and "for" is more likely still? Aug 17, 2020 at 14:46
  • I said that in my job is more likely than at my job in both cases: only if the speaker was using "my job" metonymically to mean "my place of work" is at possible, in either sentence. But I added that the working hours of my job or for my job seemed to me more likely still.

I have to disagree with the explanation in the first example. We say "I am good/methodical at my job" because this preposition is required by the adjective:

I am good at something.
I am terrible at something.
