There ought to be a word - and perhaps there is, in German - for the mix of feelings that accompanies composing and activating a holiday out-of-office message. There's smugness, of course, and a gratifying sense of laying down one's virtual tools after a horribly long shift. But for many of us, these nice feelings are tempered by the knowledge that in two weeks, refreshed but depressed, we will have to trawl through hundreds of emails, many of which will be conference room notifications for meetings about crises that have passed.

I read it as coming from a person who was overly frustrated with their regular OOO being ignored. It’s one of my pet peeves – the OOO clearly says I’m not there and to contact Bob, yet the sender continues to reply, never contacts Bob, then blows up at me when I return that their work is delayed. I would love to be able to send something like this message in the letter but it wouldn’t fly at my office.
As a part time person, I now put an OOO on my non-work days since I was getting snarky comments about slow response times. (People don’t realize I’m part time and my position is not suited at all to it.) Dude, I didn’t respond because I don’t get paid to work on Fridays.
