Pickets will be placed on the Junglebox creche and the main offices of the Ferns Diocesan Youth Services tomorrow morning.
The picket is the latest in a series of events taken by staff at the FDYS over FDYS' claimed continued refusal to engage with the employees' trade union and unilateral removal of their sick pay scheme.
Last Saturday more than 1,000 signed a petition in support of the workers including a number of local politicians and Minister for Expenditure Brendan Howlin.
SIPTU's Catherine Walsh said the rally had been a great success with many people expressing outrage against the treatment of staff at FDYS. Pickets will be outside Junglebox from 8.30am until 9.30am while the main office will be picketed between 9.30am and 10.30am.
