Seven days of talks between Bus Éireann and unions failed on Tuesday (14 March).
It says the unions did not show any flexibility on inefficiency reductions.
The Board of Bus Éireann will now urgently “re-assess what action is appropriate to safeguard the organisation,” which faces bankruptcy in May unless cost savings are made.
Says Bus Éireann: “Given the seriousness of our financial position, we always had a very tight timeframe to implement actions but we nevertheless engaged in good faith to facilitate intensive discussion, with the aim of reaching a negotiated settlement with trade unions.
“Despite their public pronouncements about engaging on addressing the high level of inefficiencies, there has been no flexibility shown during our engagement on efficiency measures.
“While inefficiencies have been acknowledged and accepted by unions, there was a refusal to accept any reduction of earnings, including unnecessary overtime earnings.
“The management team will now report to the Board of Bus Eireann to urgently re-assess what further action is now appropriate, and necessary, to safeguard the organisation and the service we provide.”
