Over 40% of staff at the National Museum of Ireland are at risk of developing anxiety or depression, according to an unpublished report into employee well-being at the institution.
The report also found that one in five employees at the institution are "often" or "always" subjected to bullying.
Another 20% are "sometimes" the victims of bullying, while one employee complained of having to deal with "bullies and perverts".
The findings are contained in 'The Work Positive Profile Management Report', which was completed last November and obtained by RTÉ's Drivetime.
The revelations have prompted calls for the Minister for the Arts to appear before an Oireachtas Committee to discuss matters at the institution and to address an allegation her Department failed to act when alerted to alleged bullying.
Separately, the museum has also revealed how it employed the services of the Dublin Rape Crisis Centre to provide Dignity at Work training workshops
The National Museum of Ireland operates four sites - The Archaeology museum on Kildare Street, where the Seanad is to move; the Natural History Museum on Merrion Street; the Museum of Decorative Arts and History in Collins Barracks and the Museum of Country Life in Castlebar
The unpublished report consists of a health and well-being survey of staff at the museum.
It was carried out by Robert Kerr, an eminent HR academic at Ulster University.
A total of 96 staff completed the survey - four in five had been working for the institution for five years or more.
There are between 140 and 150 staff at the institution.
The survey found:
- over 40% of employees at the institutions are deemed to be at risk of developing anxiety or depression; as measured by an index supplied by the World Health Organization.
- almost 70% of respondents feel employee morale is poor to very poor- with poor communication and a lack of trust at the Museum.
- Seven in ten employees want mental health support to help deal with stress and depression.
- Staff contentedness at NMI is in the bottom 20% of Irish companies.
