Industrial action is expected to cause some disruption tomorrow (Thursday 18 January) to services at the Public Record Office of Northern Ireland in Belfast.
The one-day mass strike by public sector workers will be the biggest industrial action to take place in Northern Ireland for many years.
As a result, onsite services are likely to be reduced and PRONI advises any researchers planning to visit PRONI to telephone 028 9053 4800 before travelling.
UPDATE, 18 January 7:30am
In view of snow and freezing temperatures (and the fact that most roads would not be gritted because of the strike) PRONI took the decision last night to close its doors until Friday morning.
