Two unions are taking legal action over plans to cut hundreds of jobs at Australia's largest rail freight company, QR National.
The Electrical Trades Union (ETU) and the Australian Manufacturing Workers Union (AMWU) say the company is forcing staff to apply for redundancies before a dispute about their pay-outs is resolved.
ETU organiser Jason Young says the union has asked the Federal Court to suspend the restructure process.
"We've already had to calm some of our members down," Mr Young said.
"When QR National put out inflammatory information to say that they're going to go ahead with this restructure, some of our members are going 'well we should be walking'.
"We've said we will do the right steps and we will take this to the courts." QR National says it is confident of resolving its issues with the unions through Fair Work Australia.
