In the US, to qualify for and receive Unemployment Insurance benefits you must declare and demonstrate that you are looking for paid work commensurate with your skills and expertise and are unable to find it.
If you qualified for your state's UI, and also got the +$600/week Federal add-on, on account of being laid off by your employer due to COVID-19-related closures, orders, etc and your employer has re-opened ("safely") and has offered you "your job" back, ...
... you cannot both refuse to accept it *and* continue to qualify for UI and thus UI+$600/week. Therefore, the +$600/week added to your weekly UI benefits literally *cannot* be an incentive to remain UI eligible, i.e. unemployed.
What our actual masters want is to forestall and prevent the "masses" realizing the *possibility* that their money income could be higher than private and sub-national government employers are willing to pay them to purchase the right to direct and use their capacities to work.
That they're eager to quash even the thought that individuals could have an individual *enforceable* right against the US Government to remunerative, dignified, local employment if they're willing to work, federally paid-for and locally administratered, is, of course, patent.
