Multinational timber industry giant Carter Holt Harvey has indefinitely locked out about 150 workers who are members of the Electrical Trades Union; Construction Forestry Mining and Energy Union; and the Australian Manufacturing Workers Union at the company's Myrtleford plyboard manufacturing site.
The lock out began at 2.30am on April 19.
It follows a breakdown in enterprise agreement negotiations between the company and unions.
Union members are seeking improved income protection insurance coverage and a significantly better wage rise than the company is offering.
Union members are determined to achieve a new enterprise agreement for the site that properly recognises their skills that have made the Myrtleford site a productive and profitable operation.
