Nursing staff at Árd na Gréine in Stranorlar are set to begin industrial action later this month.
Members of the Irish Nurses and Midwives Organisation and Psychiatric Nurses Association will stage a protest on May 27th, followed by a work-to-rule from June 2nd.
The action follows a ballot of members after management withdrew proposals for 24/7 on-site management at the Donegal Intellectual Disability Services facility.
The unions say staff had cooperated with major service changes over the past two years based on written commitments that out-of-hours governance would be restored.
Both unions are now calling for on-site management to be reinstated and for additional nursing managers to be appointed to strengthen safeguarding and clinical oversight.
