Transport Minister Pam Beggs today called on striking Westrail employees to return to work immediately in the interests of their future and the State's economy.
"This strike is senseless in the extreme," Mrs Beggs said.
"All other parties, including other Westrail unions, are abiding by the independent umpire's decision to return to work but the Railway Officers' Union is showing a total disregard for the due process.
"The grain harvest is being affected and hundreds of small businesses and their customers are relying on the rail system for the smooth transport of goods.
"The issue at stake is a personal one between two people and it is grossly irresponsible to hold the State to economic ransom.
"The Industrial Relations Commission is a system that workers should support in their own interests as a legitimate and independent way of resolving industrial disputes.
"In the interests of the State, the workers should abide by the Commission's direction to return to work pending the outcome of a formal inquiry into this matter."
