One of the “most important roads of Scotland could close with an incalculable interruption”, since the workers supported the attacks in response to a salary dispute.
The Clyde tunnel in Glasgow, confident in around 65,000 drivers a day, faces interruption since the control personnel have unanimously backed industrial action.
A team of 10 Whiteinch headquarters in the city is responsible for monitoring the tunnel CCTV system, ensuring that it is safe for drivers who use it to cross under the Clyde River.
They also control ventilation and respond to breakdowns among other emergencies.
GMB Scotland said its members in the team supported the strike after Cosla offered a salary increase of 3%, which the workers considered too low.
The union warned that if workers attack, the tunnel, which connects the north and southern Glasgow, can be forced to close.
Keir Greenaway, a senior organizer in public services for Gmb Scotia, said the tunnel staff were the first to vote in a strategic industrial action campaign to ensure an improved offer for all the workers of the Council.
He encouraged the Scottish government to interact with Cosla to resolve the dispute.
He said: “Council workers have again been forced to fight for a right salary while watching others in the public sector, NHS Scotland, for example, that acceptable offers are made.
“The daily life of millions of Scottish rests on the shoulders of the local authority staff and will not be treated as the poor relations in our public services.
“The team in the Clyde tunnel maintains the move of the largest city in Scotland, only an example of the essential services provided by our members.
“Without his experience and experience, one of the most important roads in the country could close with an incalculable interruption.”
He added: “The current offer adds cents to the rate per hour paid to the staff with the lowest payment, and is beyond the time for the ministers to seriously get involved with Cosla and the unions to deliver a fair salary.”
Starting with the Clyde proposal tunnel strike, the union is now planning the strategic action to obtain workers an increase of £ 1 per hour or 6.5%.
It occurs after an advisory vote of all members of the GMB Scotland Council, said that 96% of voters supported strikes if Cosla refuses to improve the 3% salary offer.
The strike dates have not yet been announced, but it is understood that at least two weeks a notice should be given to the Council before industrial action.
A spokesman for the City Council of Glasgow said: “We are aware of this vote, but we have not received a formal notification of the intention of taking industrial measures in relation to the Clyde tunnel.
“The vote was carried out in relation to national salary negotiations for local authorities, which are managed nationwide through Cosla.”
A Scottish government spokesman said: “The Scottish government does not have a formal role in these negotiations.
“However, we urge all parties involved to work together constructively and reach an agreement that is fair for the workforce and affordable for employers.”
Cosla was contacted to comment.
