Two builders holding a protest from the top of a crane near Lucan say they'll starve before they'll admit defeat.
The pair scaled the tower last night, in a row over pay for brickies at Kishoge Community College.
They're part of a group who say they're being paid less than a fiver an hour, or haven't been paid at all.
They were supposed to be carrying out work on Kishoge Community College near Lucan.
Gary Gleeson, a member of the UNITE trade union, spent last night in the crane's cabin and says he won't come down until he's paid what he's owed.
The construction company and a subcontractor involved both deny they're to blame.
The Lord Mayor, Christy Burke, has said he's willing to make his office available for talks among workers and their employers.
