Mantsho and Moshoueu, LLB students for RR University are engaged in a conversation in a train from Pretoria to Tembisa. You are in the same train minding your business but  the issue they are discussing catches your attention because it relates to one of the labour  law aspects. What sparked the conversation is that a certain Lepara who had reported to  work under the influence of an unknown intoxicating substance was told to leave the  employer’s business premises and never to set his foot there ever again. Mantsho and  Moshoueu think that the employer’s conduct amounted to an automatically unfair dismissal because the employer did not afford Lepara an opportunity for a fair hearing. A   lady next to you, Lefofa who is studying Journalism at the same University nods her head  in agreement with Mantsho and Moshoueu.  Advise with reference to the relevant authority whether the view shared by Mantsho, Moshoueu and Lefofa is legally correct, give reasons for your answer and define an  automatically unfair dismissal.
