But "employment" is tracked as a binary, not as a "number of jobs someone is working".

So if person A takes 3 jobs just to get by, there are fewer jobs left for person B. (Not quite 2 jobs less, because it's not perfectly zero-sum, but generally at least 1 job less.)

So while I certainly wouldn't make the claim strongly, as I don't have any data, it would at least make sense for the lack of living-wage jobs to increase unemployment rates.
