Please explain

‘I have left my job’ or ‘I left my job’.

What is correct?

Don’t worry. It is OK to use either one or another.

Hi.

If you left your job recently, you can use either. If you intend to say that you have left a job before in general, you can use either. If you intend to say that you left a specific job at some time in the past that is not recent, use the latter. For the first two ideas, I would prefer the present perfect.

Thanks for nice explanation.
