The Minister for Community, Culture and Leisure says he's disappointed there's been no resolution to the bus driver dispute despite a glimmer of hope this week.
Unite the Union had recommended that drivers accept a new offer that was made but a ballot couldn't be completed by yesterday's deadline.
It's believed this was down to a mistake with the papers.
The workers are being re-balloted and a decision is expected on Friday.
Drivers are due to strike for 12 days from Saturday and contingency timetables have been put in place for the TT fortnight.
Graham Cregeen says it's an unfortunate situation:
