Luas dispute more about ideology than economy
The extraordinary attack by Siptu president Jack O'Connor on disputes troubleshooter Kieran Mulvey was a pretty low blow.
The director general of the Workplace Relations Commission is a revered figure in the industrial relations landscape, due to his strong track record as an honest broker. Mr Mulvey has also served the trade union movement with some distinction over his long career.
Mr O'Connor's call for Mr Mulvey to resign was a kneejerk response without merit. However, the call did highlight how tensions have risen as a result of the ongoing Luas dispute.
