Unemployment Insurance is not distributed by insurance companies. This is done through the state you are currently in. Look it up for your specific state. Each time an employee is put on unemployment from your business your insurance rate goes up. It works very much like regular insurance. This is why companies try to deny benefits as much as they can. They don’t want their rate to go up.
