WoolProducers Australia has delivered a blunt message to the dissenting minority on the AWI board: "play as a team or resign".
It follows another public flair up between members of the board, with Wal Merriman and Chick Olsson last week voting against a board motion of confidence in chairman Brian van Rooyen.
The vote followed public calls from the Australian Wool Growers Association for Mr van Rooyen to be replaced as chairman by Roger Fletcher.
But WPA president Don Hamblin says the dissident pair should "get back to work and stop wasting our time".
"Time spent on agri-politics is time not spent on increasing the price of wool or lowering the cost of production, which is what we pay you for," Mr Hamblin said.
"The AWI board is not a political prize or parliament for agri-politicians to fight over.
"It is there to oversee a multi-million dollar research and marketing company for its shareholders.
"Directors should understand their obligations to put the company and shareholders first.
"The choice is very simple for a director who feels he or she can’t support the company or its chair – get behind the board and get to work, or get out."
WPA says it has full confidence in the AWI board, chairman and the governance procedures of the company.
