The postal workers’ union in Australia has said it fears for the safety of workers amid a possible public vote on same-sex marriage as the have to deliver the campaign materials to people’s homes. The Yes campaign said to Australia Post that it must abide by its rules to not deliver anything that “does not meet current community standards of reasonableness, honesty and decency” nor anything considered “defamatory or offensive”. The Communications, Electrical and Plumbing Union (CEPU) wrote to Australia Post reminding them that delivering is still their duty which they cannot disobey. “We are seeking clarification of Australia Post’s plans, if any, to mitigate against a heightened risk to employee welfare while undertaking duties associated with this extraordinary process,” CEPU’s Greg Rayner said according to the publication. The No campaign said it had been blocked from spreading their campaign materials online, so post is the only way remained for them to agitate.
