People are naturally impatient, and when they are looking for answers to their questions, they want them as soon as possible. That’s why some recipients of your auto-reply messages won’t be happy if they just get some information that you are gone and have to wait for your return. In such cases, you need to provide an alternative point of contact for urgent matters.
It definitely sounds like something my boss would write and I laughed at it. In our work, everyone thinks that they’re a special emergency all the time. Stopping to think “if I don’t have this in the next two days what will the actual consequences be” is a thing that should happen more but doesn’t.

Here’s my OOO nightmare: when I was a graduate intern a few years ago, there was a volunteer with severe, marginally treated mental health concerns. Her behavior toward me was inappropriate to the point that my school assisted me with a safety plan. I obviously blocked her on everything I could think of. Unfortunately while I was on winter break she emailed my agency address from an account no one knew about, got my OOO message, assumed it meant I was open to communicating again, and proceeded to have a monthlong meltdown in my inbox when I didn’t respond. To this day I am grateful for my city’s utter lack of public transit, which prevented her from trying to find my home and family.
If you have critical projects that can’t wait until you return, offer a communication option like text messages, suggests Reeves. “I have found, to my delight, that people really are judicious about texting you while on vacation,” he says, with one caveat. “Don’t put your mobile number in the away message. That way, only people who have your mobile number can text you. And those are the ones you care most about.”
