Dublin Bus drivers are considering having a day of no fares as part of industrial action.
Dermot O'Leary, the General Secretary of the National Bus and Railworkers Union, said it's one of the options that the drivers will discuss next week.
Industrial action is being discussed in response to the Labour Court's ruling that the drivers should receive a 8% pay rise over three years, while they were seeking increases close to 15%.
Other options for industrial action the drivers may explore are all out strikes and 24 or 48 hour work stoppages.
The ballot of SIPTU members in the Dublin Bus Traffic Grade is expected to take place next week.
