They also protested what they said was hospital mismanagement that makes it difficult to recruit and retain quality staff.
"We're seeing a lot more patients lately because Calais Regional Hospital has had some departments close. We are seeing the brunt of those patients coming here so we feel like we are really working hard and getting no investment by our managers who are making financial decisions that are questionable as far as we are concerned," registered nurse Berta Alley said.
The nurses said some of them are long-time employees who have committed their lives to serving the hospital and community. They said many of those long-time nurses haven't seen a pay raise in years.
The hospital's administration issued a statement saying, "a fair offer was made and the union chose to reject it."
"Down East Community Hospital is committed to safe and adequate staffing and all shifts are fully covered," hospital officials said.
