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’m the same. I don’t find it condescending, it’s kinda eye-rolly but also kinda charming! I get why it could be annoying if you need info quickly. But really, why not inject a little silliness into boilerplate messages like this, as long as it’s not disrespectful or really out of step with your field culture?

We’re always busy. Sometimes we’re too busy even for work. This is where out of office message comes in.
I agree about the out of office reply. Made me laugh. Given that I work a high stress job, I can always use some laughter, so I actually don’t mind it.
