Managers at Cargill Foods in Wagga Wagga have held crisis talks with meat union officials to try to defuse a worker dispute that risks seeing 400 abattoir workers locked out next week. The lock-out is expected to last three months, starting tomorrow [Thursday]. The plant is 50 years old and breakdowns have led to a growing number of stoppages. Owner Cargill Foods is not prepared to push for the upgrade the abattoir needs, which would cost A$30m (US$15.8m), unless workers accept a new enterprise agreement.
