About the “overshares”: You linked to a previous column that mentioned this point, “Sometimes the over-sharing of plans can even come across as suspect — similar to how when someone’s calling in sick with genuine illness, they usually just say, ‘I’m going to be out sick,’ but fakers will generally give you a long list of overly specific symptoms, like they feel they have to convince you.”
Of course, every message sends a message, even a barebones OOO that seems to say nothing more than that you’re away until next week, so why not try to inject a little personality? You could get quirky by giving your auto-responder robot a personality. You could dispense with words altogether and substitute a gif or emojis. Or how about a little retro concrete poetry – you know, where you arrange your words on the screen to form an image of a palm tree or a pina colada? It might be worth noting here that the amount of personality you inject depends on your trade. What earns you cachet in the creative industries might backfire in the financial sector, for instance.

My coworker went out on disability for surgery and left an ominous OOO saying she would be out and did not have a return date, multiple people contacted me bc they were freaked out. The message suggested people reach out to me in her absence and spelled my name wrong, we’ve been working together for 4 years.
“I will be away on a vacation from June 3 to June 14. For urgent queries, you can call [person] at [phone number].”
