Democrats appear to be unmoved by fresh demands from the largest federal employees’ union to reopen the government, a sign that the shutdown stalemate between lawmakers will continue as government workers increasingly feel the pain during the process.

Over one million federal workers are going unpaid as the impasse drags on and some are turning to food pantries.
