A picket will start outside Cherry Orchard Hospital this morning following a dispute with an electrical contractor.
The Technical Electrical and Engineering Union mounted pickets outside St. James' hospital last week over a pay row with a contractor.
They say some companies are paying 3 euro 50 an hour less than the standard wage for these jobs.
National secretary for the construction sector of the TEEU Brian Nolan says the picket will expand from this morning.
