We recently dismissed an employee with good reason. We told him that, as per the company policy, the fact he was dismissed was strictly confidential and that colleagues would not be told the reason why he left. Obviously, they would probably be able to work it out... The issue is, one of the staff involved in the decision has told someone else that he was dismissed, and the news has now spread around the company. Do we need to reach out to the dismissed ex-employee to tell him, as we previously informed him in writing that no one else would be told? Thanks!
