The union representing Toronto city hall employees says Mayor Rob Ford's decision to report a bomb threat to the media violated city policy, putting workers at risk.
The union had filed a grievance against the City of Toronto, saying Ford acted irresponsibly and ignored corporate policy that outlines the appropriate line of communication when there is a security threat or suspicious package.
On Monday, Ford told reporters he received a threat that demanded he resign his post or a bomb would explode at city hall.
The president of Local 79 of the Canadian Union of Public Employees says the city's policy wasn't implemented properly, and Ford's decision to talk to the media could have caused chaos and pandemonium.
Tim Maguire adds that his goal is to prevent a similar chain of events in the future.
He says he also wants to ensure that those who issue bomb threats aren't emboldened by publicity.
The union is asking the Ontario Ministry of Labour to investigate.
