Update 2.50pm: Siptu have warned of a "a long and damaging" industrial strike because of the "intransigence" of management and the Department of Transport.
Siptu Transport, Energy, Aviation and Construction Division Organiser, Owen Reidy, said: “Unless the approach of management and the officials at the Department of Transport changes radically, Dublin Bus would seem to be set for a long and damaging period of industrial strife.
“The obstructive approach of management is evident in the announcement this afternoon that all Dublin Bus services will end at 9pm tomorrow. This is an unnecessary move which will just further inconvenience the travelling public. Dublin Bus drivers had committed to completing their shifts, even if this meant returning buses to their garages after the official start of strike action at 12.01 a.m. on Thursday.
He added that there has been no talks with the Department of Transport or Dublin Bus management, apart from a one-hour meeting, since workers voted in favour of industrial action last month
He said: "At this meeting management simply informed our union representatives that it was not willing to improve on the terms of a Labour Court recommendation which had already been categorially rejected by our members."
SIPTU Organiser, John Murphy, said: "Dublin Bus returned to profitability in 2014, passenger numbers are up, revenue is up, fares are up but pay has remained stagnant. However, over the last six years the state subvention has been reduced by 24%. Even worse is the situation whereby €2 million of the profits earned by Dublin Bus was taken last year by the National Transport Authority rather than reinvested in the company. This sum could have gone some way towards meeting the Dublin Bus workers’ pay claim.
"By their actions the Department and management would seem to be intent on sleep walking into a prolonged dispute which has the potential to create chaos for the travelling public and do long term damage to the company."
Earlier: Dublin Bus services will terminate on Wednesday night because of planned industrial action by drivers.
Unions have served notice of strike action on Thursday and Friday.
The company says this leaves them with no option but to terminate all routes at 9pm tomorrow to ensure the safe return of buses to the depot.
Drivers are due to walk off the job in three 48-hour stoppages this month - on the 8th and 9th, 15th and 16th, and the 23rd and 24th.
The unions representing staff say it is only fair that bus drivers and Luas drivers are paid the same wage.
