In a general sense yes HR issues are tied to legal issues. For example I have a client who wanted to dismiss an employee via text message, which is a legal issue and could end up with your company being sued for unfair dismissal. It is important to always have the legal aspect of HR covered when dealing with employees for instance understanding the National Employment Standards which set out rights and entitlements , that are legally enforceable. Having good HR policies and procedures means less chance of litigation. The one area I wold like to remind employers is that of social media. It is good to also have a social media policy about what can be posted on to personal website relating to work issues and work functions. The better you communicate your policy the better you will be covered from a legal point of view.
