De Kollega's maken de brug! (1988) on Netflix

Plot summary

November 11, Armistice Day, falls on a Tuesday. When that happens, the public service's staff can expect the preceding Monday off, but only once a formal ministerial decision has been taken. The paperwork works its way up through the hierarchy to the office where it must be read, and there it is left unread. Paul Tienpondt, Jean De Pesser, Gilbert Van Hie and the rest of the staff therefore come in as usual and learn that they could have stayed at home. The day gets worse. Work in progress and clumsy handling block the exit by both the lift and the stairs, leaving the colleagues shut in on their floor. There seems to be no telephone, and no one outside can hear them.
