Toll Holdings Limited (ASX:TOL) could face a 72-hour strike after the Transport Workers Union won the right to vote on industrial action.
Australia's largest transport operator may be temporarily halted, with about 8500 workers from Toll Group to take part in the vote after the Fair Work Commission approved a ballot.
Workers at more than 400 yards will be balloted by the Australian Electoral Commission on forms of industrial action, including stop-work action of up to 72 hours.
The union wants a guarantee that employees of companies contracted by Toll are paid fair wages.
It also wants Toll to guarantee it won't create separate business units with lower pay rates and different safety standards.
Toll generated a net profit of $195.5 million in the first half of fiscal 2013.
