Members of SIPTU and the NBRU have agreed to talks at the Workplace Relations Commission aimed at resolving the row at Bus Eireann.
It means its members won't be taking to picket lines on Monday in an all out strike.
Workers had planned to walk off the job in a row over a €12m cost cutting plan. Bosses insist the measures are necessary to save the company from going bust by May.
There had been fears the strike would be travel chaos in the city.
Thousands of people travel into Dublin every day for work and college. Those numbers would use other forms of transport meaning trams, trains and the roads would be completely clogged.
The unions have confirmed they have agreed to enter talks at the WRC, so have put their strike on the back burner for now.
Bus Eireann bosses say in light of the strike's suspension, they will withhold the implementation of their cost saving measures while the talks continue.
