The families arrived at the staff car park at the Royal Gwent Hospital, in Newport, south Wales, at the weekend.
They had been given an ultimatum by NHS managers to leave by 4pm on Tuesday. However, there was no sign of an attempt to leave before the deadline passed and the Aneurin Bevan University Health Board, which runs the hospital, has begun legal proceedings to eject the group forcibly.
Hundreds of NHS workers, including doctors, nurses and emergency staff, have been forced to find alternative parking since the travellers arrived on Saturday.
Hospital managers contacted as many staff as possible on Sunday in an effort to ensure disruption was kept to a minimum when workers returned to work after the weekend.
The group, who have taken up around 65 of 300 spaces, are thought to be Romany families and have told officials they are in the area to attend a funeral.
The families, with 14 caravans, claim to be from Paris and Nice and have said that they do not intend to stay long term. According to some reports, they plan to move on Wednesday.
Julian Hayman, a spokesman for the hospital, added that security staff would remain in the car park and that the situation would continue to be monitored.
