THOUSANDS of drivers are facing traffic chaos as strikes could close a major Glasgow road.
GMB Scotland is set to ballot the team controlling the Clyde Tunnel in the city on industrial action after a council pay offer was overwhelmingly rejected.
COSLA has been handed the formal vote on the strikes this week, with the vote on the industrial action set to take place next week.
Due to the potential walk-out, the union has warned that the action could shut down the tunnel while workers strike.
Keir Greenaway, GMB Scotland senior organiser in public services, said: “The workers at the Clyde Tunnel ensure thousands of motorists travel safely and without delay every day.
“They keep the city moving and without their expertise and experience, one of Scotland’s most important roads could close with untold disruption.”
Hitting out at the three per cent pay offer made to council workers, Greenaway said it was "unacceptable".
He added: “The offer is nowhere close to matching the commitment of council workers, adding pennies to the hourly rate paid to the lowest-paid staff.
“The frontline roles of our members on the Clyde Tunnel and their colleagues across Scotland’s councils deserve to be properly recognised and fairly rewarded.
“They have been offered an annual increase below inflation as household bills continue to climb.
“No one, not least the councils, could have been surprised when it was overwhelmingly rejected, and they should not be surprised when our members take whatever action is necessary to be paid fairly.”
Glasgow's Clyde Tunnel is used by around 65,000 vehicles per day.
A Glasgow City Council spokeswoman said: “We will await the outcome of the ballot and officers will continue to engage with unions.”
COSLA has been contacted for comment.
