Foster's beer makers are worried about their job security after finding out through the media that the iconic Australian company will be taken over by British-based brewer SABMiller.
Foster's Group has backed a $12.3 billion takeover bid by the global brewing giant and say it will be good for local jobs and the company's branding overseas.
About 250 beer makers at Foster's Abbotsford brewery in Melbourne were not notified about the takeover by management, but found out about it through the media, said Jess Walsh, Victorian secretary of the United Voice union.
She said staff are concerned about foreign ownership of the company and whether the new owners will understand the cultural and historical significance of the brewery.
"The most important thing is that whoever owns the company understands the significance of the Abbotsford brewery in production but also culturally," Ms Walsh told AAP on Thursday.
