A restaurant owner on Cape Cod told us she would interview wait staff and then they would never respond to calls for hiring etc. They just needed to show their unemployment office that they were "looking".
I think unemployment laws vary from state to state.
This was in NH. I think in NH you have to actually get a job for at least ONE day.
In MA(being a very liberal state) you probably just have to say you were looking for work to qualify.
I guess that is why the unemployment rate in NH is 3.0% and MA is 5.0%
FYI, NE is 2.2%, UT is 2.6, ID & SD 2.9
NV 7.7, CA 7.5, NY 7.4, CT, NJ, NM 7.0
