The Leader of Fianna Fáil is accusing the Transport Minister of acting like Pontius Pilate
Shane Ross is facing criticism for his handling of the dispute at Bus Éireann - after management announced a series of cutbacks earlier this week.
Workers are threatening to strike over the changes.
Micheál Martin says it's time for Minister Ross to step up to the plate: "Bus Éireann goes to the heart of public policy, particularly in relation to the regions and to rural Ireland but he needs to step up to the mark and get a handle on this issue.
"I think he is adopting a Pontius Pilate, hands off approach, which isn’t in our view adequate and satisfactory."
A former Transport Minister has warned Shane Ross not to wave his cheque book at the Bus Éireann dispute.
Noel Dempsey says a solution needs to be found urgently, but claims the Government is not responsible for the day-to-day running of the firm.
Workers at Bus Eireann have hit out at cuts to their terms and conditions as part of a cost saving plan.
They are threatening to strike over the changes.
But Noel Dempsey says State intervention is not the way forward:"If Shane Ross or the Department or the Government move in to start waving a cheque book about there will be no real changes within Bus Eireann, probably no real changes that are necessary in work practices.
"You end up with a situation, three, four, five years from now, where you will be back at square one."
