Work Blackout
Related to times spent actively "at" or "doing" your work in relation to your job and livelihood when you have absolutely no memory of those deliverables or the time spent on them. This is not meant to imply that you are imbibed or physically impaired in any way. You are simply so over-worked, that you have entered a mental state that no longer accepts memories of actions being executed, discussed, emailed, delivered, etc.
Can you send me that Power-Point presentation I sent to the team a few weeks ago that was a training guideline for strategic improvement? ...This is it? I don't remember writing a word of this? Like, I wrote this and emailed to you? I must have been in a complete Work Blackout when I did this!? Gets the point across though, right?
