The OPW is calling on local community groups to "reconsider their protocols"
The Office of Public Works (OPW) says it welcomes the recent progress made with local community groups which has seen essential services allowed access to Castletown House and Estate.
This has permitted pest control to service the site, heating and plumbing issues to be repaired and refuse can now be collected.
However, from the outset of these events the OPW also says it has been concerned about the "challenges arising for its staff in Castletown including being made to feel intimidated while accessing their place of work."
The Services, Industrial, Professional and Technical Union (SIPTU) have now formally raised these concerns on behalf of their members.
The OPW says "unless there is more progress made and OPW staff are allowed to safely access their workplace, this will result in the House and Estate being forced to close", on safety grounds.
The OPW is calling on local community groups to "reconsider their protocols and allow for OPW staff, which along with third-party contractors, are essential to the overall maintenance and upkeep of the House and Estate."
Kfm has contacted the Save Castletown Group for comment, and will be covering the topic on Tuesday morning's Kildare Today show from 9am.
