Air traffic controllers working for Highlands and Islands Airport Limited (Hial) are being balloted on strike action in a dispute over pay.
Controllers who are members of the Prospect union rejected a 2% pay offer made last year.
The union said it was balloting its members because efforts to resolve the dispute had failed.
Hial, which operates 11 regional airports, said it was committed to continuing “constructive discussions”.
