Staff at Roscommon County Council are holding a fourth day of strike action today, in a dispute over flexi time working.
It comes after the council was criticised for its approach to the issue, by the NOAC - the oversight body for local authorities.
The strikes are organised by the Fórsa trade union, and are being supported by SIPTU.
The NOAC has recommended that unions suspend industrial action if Roscommon County Council allows 'family friendly' working practices.
Peter Nolan from the workers' union Fórsa believes the council must now respond.
