I'm going to guess the real meaning of this is: workers are taking second jobs online, not disclosing it to their exploiters and refusing to do overtime because it overlaps with the other job, so the exploiters are then counting any extra revenue they could potentially have obtained from unpaid overtime as their "loss".

Dear lord it's actually even stupider.

Apparently, if you work remotely from a place with a cheaper cost of living than where your work is, you're somehow stealing from your boss. Employers are mad that they don't get to underpay you for having better living conditions even though it literally costs them nothing.
