All outdoor staff in Clare County Council, who are members of the SIPTU trade union, are being balloted for industrial action in a dispute over new vehicle usage and vehicle telematics policies.
Last month, transport workers in the council began industrial action in the form of a work-to-rule.
This escalation would involve their colleagues in other outdoor divisions engaging in supportive industrial action, which SIPTU said would result in significant disruption to the delivery of services.
The union has claimed that the new transport measures have been introduced without proper engagement and has accused the council of refusing to engage with the State's own industrial dispute resolution system.
"This ballot is the direct result of Clare County Council management consistently refusing to comply with the agreed procedures for resolving disputes, including attending the Workplace Relations Commission (WRC)," said SIPTU Organiser, Arek Muszynski.
"Such behaviour is unprecedented in the public sector and undermines the long-established dispute resolution system that all council employees rely upon," Mr Musynski said.
Clare County Council has been contacted for comment.
The council previously said that as part of the implementation of the new policies, it undertook a 12-month engagement process with all trade unions, including SIPTU.
"Clare County Council strongly refutes the assertion that it has failed to meaningfully engage or comply with agreed dispute resolution procedures," a spokesperson said at the time.
The council said the new policies are being implemented for reasons of climate change, insurance and health and safety, among others.
"The core issue is that the practice of employees commuting to and from work in council vehicles, including velocity patchers, articulated trucks and litter vehicles, is not permitted," the council previously said.
