There is no isolated reason or the solution to this kind of problem in real life. Hence, in course of the career the supervisor has to interact with individuals in his/her team and offer constructive advises to ward off any habit in the making, which could be detrimental to the said individual or to the team as a whole. Sudden discovery and abrupt terminal decision , unmindful of root causes , does not create the correct working environment in an organisation. Therefore, in my opinion, there should be silent observation of each individual by his/her supervisor, there should be root cause analysis of any unnatural behaviour through across the table discussions, sincere advises and then a time bound improvement plan- failing at all these steps, the terminal decisions should be taken. After all the employees are the most valuable asset of any business and incorrect handling of these kind of situation leaves behind wrong impressions in the minds of other employees in the organisation.
