Epic fail

Motivational work poster fail! (An email I received today)

Please forward to your teams.

It was brought to my attention that the posters we have placed near the door to encourage you to connect with your managers advocate and experts on this floor, have been defaced. (Defacing company property is gross misconduct.)
This is so disappointing when I think of the challenges we face as a department to work towards where we need to be in terms of the experience we create for our customer, that one or more of us are prepared to cause the inconvenience and cost of having to replace expensive large colour prints, that are here for your benefit.

As we are not able to identify who did this unfortunately I have had to blanket brief you all, and for those of you who continue to come to work every day with the right work ethic and behaviours, Thank You, and I apologise to you for having to hear of an example where your colleague has let your group down, and for the time this has taken away from what I have been able to do to support you whilst you do your best for our customers today.

Regards,

Kate.

Are there really people in the world who would write an email such as this (without having a wry grin on their face)?
The thought that someone wrote this in earnest actually makes me feel sick. Has someone killed the author yet?
