That's a second thing
Do you think one can say something like "That's a second thing" meaning that the subject is not so important as something that was said earlier?

Eg.
- As far as management...
- That's a second thing. If the company doesn't pay its workers, management doesn't really matter.

Thank you

Answer

You'd say 'that's a secondary issue/ problem' rather than 'a second thing'.

If we're listing issues we might say 'and another thing ...' if we remember something we want to add to our list.

Answer

I agree with Rob. Another way to say it is “secondary matter”.  There is an idea that does use your phrase in a similar way: “first things first and second things second”, but it is said quite rarely and “second thing” is never used separately from that that I can think of.
