There is no requirement unless you want to qualify for benefits. You are always free to not work. What you are NOT free to, however, is the money others have earned.
Simple faithful execution of the law is a qualification. On what basis does any State deny or disparage our privileges and immunities regarding employment at the will of either party for unemployment compensation?
And, you must agree with me that unemployment compensation can solve simple poverty in a market friendly manner since you have no arguments against it, only your appeals to ignorance of the law.
