Democratic leaders want answers on a path towards compromise on a host of federal budget fights before the end of next month.
VA has conducted a poll of federal employees every year since 2006, but won't distrubute one this year amid multiple reforms to the workforce.
Department leaders last month uncovered more than $100 million in duplicate government payments for medical services.
About 80% of VA's roughly 450,000 employees are union members, but the department will no longer honor its contracts with the bargaining units.
