> First of all, I'd like to figure out how we can identify someone working more than we are aware of. Generally it would be fine for me (/us) what people do in their non-work time, but if it affects our work, then it's not acceptable. So how can we identify such a situation?
The question indicates the OP doesn’t have a way to measure performance, and instead focuses on identifying employees who might have other jobs.

I must have misunderstood what you meant by this:
> We aren't talking about people holding mulitple low-paying jobs to make ends meet. It's mostly people in well payed positions taking advantage of being remote.
One could read “taking advantage of being remote” more than one way, but in the context I read it as people already paid well taking advantage of their employer.
