Around 140 jobs are at risk at BT in Aberdeen after the firm confirmed it is considering closing its base in the city centre.
The communications company has begun consultation with office-based staff at New Telecom House in College Street.
A spokeswoman said the firm use about 10% of the building and described lease renewal as costly.
If the closure goes ahead, BT said they will “look at all options” for affected employees, including helping them find roles at their other sites.
A BT Group spokeswoman said: “We’ve started to consult with a small number of office-based colleagues and their union representatives on the proposed closure of New Telecom House.
“We only use about 10 per cent of the building and the lease renewal is costly.
“No decision has been made but if the closure goes ahead as we propose, we’ll look at all options including helping colleagues find roles within BT Group sites, such as Dundee – which we announced as a key location last week.
“There’s no impact to customers and plans to extend Aberdeen’s full-fibre network are not affected.”
