Bus drivers have confirmed they will be working to rule as of tomorrow.
The decision was made after a last-minute meeting was held earlier today in an attempt to stop the industrial action from taking place.
The meeting between Unite the Union and the Department of Infrastructure was based on a dispute over annual leave and overtime.
Union boss Eric Holmes says staff and management did not come to a resolution and another meeting will take place on Wednesday.
