Dismissal by text will almost always be an unfair dismissal

“However, Mr Hain was notified of his dismissal and summarily dismissed by text message. I do not accept that a text message is an appropriate mechanism to advise an employee of dismissal and the reasons for it. The purpose of such notification is to trigger other incidents of procedural fairness such as an opportunity to respond to a reason for dismissal based on capacity or conduct. An employee who is notified of a dismissal by text message and simultaneously informed that the dismissal is immediate, has not been notified of the reason for dismissal in the context of s. 387(b) of the Act and the related provisions relevant to procedural fairness.”
