Demot O'Leary of NBRU very clear on RTE radio this morning.
This action was not taken by the union. Persons involved to stop and return to work
Twitter reporting picket at Clontarf Rd persons holding handwritten signs, photos from Limerick showing persons holding handwritten signs outside on one side of station, printed signs other
If you heard the speeches it was well planned action and coming since Wednesday, don't think it was the NBRU but they heard it as well.
However I believe it ended a lot sooner than some had planned!
