Depends entirely on the work. If it does not require concentration, I don't think it matters at all.

If it affects your ability to concentrate and focus it obviously is a problem and I think you should just stop entirely.

Agree. If you are paying attention to the podcast while mopping the floor, there is no problem. But if you are doing reasoning work you are shortchanging either the podcast of your work, and in my experience often both. When I was still working (I'm now retired) I would listen to music while programming. Music seems to occupy a part of my mind that is not required for programming, and often even set the mood I needed. But a podcast? No.
