The National Bus and Rail Union (NBRU) says their members in Dublin Bus are prepared to see their strike through to the bitter end.
Drivers are staging the second half of a 48-hour strike today.
Some 400,000 commuters face disruption again today, as services are suspended until tomorrow morning.
Gardaí say motorists will not be permitted to use the bus lanes on days of strike action.
Bus lanes will be reserved for other bus services, as well as for emergency vehicles, cyclists and taxis.
Nitelink services will also not operate Friday night or Saturday morning.
The five unions representing drivers are due to meet next Thursday to discuss their next course of action.
Two more 48-hour strikes are planned to take place next week and later this month.
Further stoppages are due on Thursday September 15th and Friday 16th, and again on Friday 23rd and Saturday 24th.
Dublin Bus says it is "disappointed" that the industrial action is taking place and that customers are being significantly discommoded.
General-Secretary of the NBRU, Dermot O'Leary, describes how drivers felt after yesterday's strike action.
Meanwhile, a cabinet minister has admitted the Government does have the power to allow civilians to use bus lanes during the Dublin Bus strike.
But Leo Varadkar says there are good safety reasons for not doing so.
Mr Varadkar served as transport minister during a three-day strike in 2012.
He says it is up to Transport Minister Shane Ross to consider the measure now - but there were good reasons he did not do so.
