Not much you did not work long enough to claim working . Where does your other income come from. Why do you think you should get anything back from working 3 weeks? You are doing your family a dis-service working for this short of time expecting something in return.
We have enought problems in this world with people trying to get something for nothing. I am sorry if I seem cold it's just that some people really want to work and take care of their children and they deserve a kick back. Ask yourself really what have you done?
