The Irish Times is suggesting that any balloted strike would not start until late next month. I can't see Bus Éireann surviving until late next week at this rate. Although, if Bus Éireann collapses which is getting very likely, all bets are off.
I reckon the most likely outcome of all this is Bus Éireann getting a wedge of government money to wind up Expressway which can probably be pushed past state aid regulations. There is no way anyone in their right mind would buy Expressway - it's not worth anything. Their only assets are licences for slow bus routes and staff who are very generously paid compared to any competitors. This does seem like a valuable asset.
Jamie2k9 is right - nobody is going to pay any attention until there is a threat of serious disruption to Dublin city transport. Nobody powerful really cares about transport services mainly used by students and elderly people in the regional cities.
