Unannounced Absence

After being late to work twice in the past 2 months, the head of our regional office sent me a lovely communication in 15 point Calibri type. I haven't heard back since my response.

Salty Dog- Given the situation yesterday has occurred twice within a short period of time, we need to identify how to prevent this in the future but also the consequences if it happens again. I am not interested in the how/why this occurred, but only on a solution. You are a very talented individual with a great future ahead of you. As a manager of people and a leader on the client team, however, your negative actions have an impact on others. Let Daniel and me know how you propose to fix the problem and the three of us will get together afterwards. Marvin

Marvin- 

Thank you for your email. It tends to be more difficult to find solutions to problems or prevent specific events without taking interest in their underlying causes, but let’s give it a shot. Since the problem is unannounced absence, I will ensure that all future absences are announced. I hope this helps. 

If this solution suits you, I suggest that you and Daniel appraise the negative impact of an unannounced absence and work out appropriate consequences, which we can discuss at your convenience. If you believe there is a more effective preventative measure, I would be happy to discuss this as well. 

Please let me know when you would like the three of us to get together and I will get this meeting on our calendars ASAP.
