I know from close friends that it most definitely runs out sooner rather than later. You have to re apply and demonstrate that you are looking for work. How long it should last is a matter for discussion but at least it’s tied to work.
Uh I think it got extended for a 100 weeks or more. Further I have been told by workers for years that people they know avoid work to stay on unemployment. I know personally of deadbeats who turn down work because the unemployment checks are coming.
As for the requirement that you look for work? You go to a dozen places that you aren’t qualified for or are not hiring. You check off your list.
