Bus Eireann workers have cancelled their planned strike for tomorrow, following marathon talks at the Labour Relations Commission.
Both sides in the dispute over cost-cutting plans have agreed to engage with the Labour Court instead.
Bus Eireann said it will defer the implementation of its cost-recovery plan pending the outcome of that hearing.
They informed staff in December that it would be introducing changes from January 13, but unions argued the changes were made without negotiation and balloted members to take action.
The cost-cutting plan includes reducing overtime rates from 1.5-1.25 times; the working week for clerical and executive staff moving from 36 to 39 hours; reducing annual leave by three days this year and in 2014 and 2015; and a one-third cut in other allowances and expenses.
The company has welcomed the union's decision not to go ahead with strike action.
Andrew McLindon, a spokesperson for the firm, has said it is a positive development.
