Union members have accused Aberdeen City Council of withholding information over asbestos in city schools.
It was revealed earlier this week that 25 people were allowed into Bridge of Don Academy after asbestos was disturbed during maintenance last month.
Members of Unite the union agreed yesterday to enter into a collective dispute procedure over claims management failed to answer questions on this incident and one at Hazlehead Academy last week.
The move could lead to industrial action at a later date.
Unite regional officer Tommy Campbell said refusal to reply quickly to concerns is “alarming” and they need “immediate, open and transparent answers”.
He said: “It leaves Unite wondering if the council are withholding answers to avoid any further criticism of the council failing to follow their own asbestos health and safety procedures in other work areas, either before or after the incidents at Bridge of Don and Hazlehead academies.”
The union asked questions of the local authority in the last week, including whether the existence of asbestos was identified before the job at Hazlehead was started, and whether anyone was potentially exposed to the asbestos at that time.
An investigation report into the Bridge of Don incident reveals no emergency response took place because the line manager “forgot” about the incident for five days.
Officers told the union that weekly engagement meetings take place with all trade unions and that members are welcome to raise any questions and make requests for information at this meeting.
The council said it takes matters relating to health and safety “very seriously and is dealing with Unite the Union’s concerns internally at management level and externally via the Health and Safety Executive”.
The council spokesman added: “Twelve members of the trade unions now sit on the staff governance committee which has health and safety within its remit.”
