I made a genuine mistake at work I pressed send for a generic email about a detention to a child's parent due to 4 minor incidents over the term. They are supposed to be called beforehand when they have 2 negative marks, in the run up to Christmas this was an oversight and didn't happen so the first they heard was the email.
I apologised profusely to the parent but they were extremely unhappy. They weren't shouting but I could tell in their tone they were furious and kept saying the communication wasn't good enough.
This was then made even worse when I spelt their child's name wrong in an email after the meeting.
I feel that these were two genuine mistakes and all I can do is apologise as I can't go back in time. I just don't want this to carry on for the next week and a half before we break up with the parent still being annoyed.
