Context: Finally , I called the United reservations number and reported the Dulles domestic check - in problem . The representative placed me on hold and checked with IAD operations . She came back on line and told me that there was a shortage of employees that day . I was very satisfied with that answer , though this did n't excuse United management 's responsibility to at least direct passengers , employees , and contractors to keep the lines moving .
