Zoey works for a disability support service and is responsible for ensuring workplace procedures are up to date and accurately reflect workers' legal and ethical requirements. She has had to make quite a few changes to existing workplace procedures and sends them out to all staff that will be affected by the changes, requesting their feedback. Zoey understands that she can't possibly cover every work situation or potential conflict or issue in these procedures, so she tries to ensure that these procedures provide workers with good general advice. Zoey asks Joseph, the Human Resource manager, for his advice on what situations would require referral, both within and external to the organisation. Joseph informs Zoey that this will require some thought, so they sit down together to go over all legal and ethical requirements. List three instructions relating to the use of newsletters and broadcasts that Zoey should include in the workplace's communication policies and procedures
