When it comes to professionalism, keeping things short and to the point is a good idea. What’s more, if you write a short auto-reply email, you don’t spend too much of the limited time you have left before your vacation.
But this is where it becomes a power thing. The OOO person says that everyone else wants stuff from them that the sender can’t get elsewhere and you need to grovel to get it from them.

When you’re trying to contact someone on a matter of importance (or even urgency) on one side of the equation and you find out via an autoresponder that they are away for vacation, it can be incredibly frustrating unless they’ve done the front-end work beforehand. (I’m speaking from personal – and recent – experience here. And worse, there was no auto-responder set up. I had to use the – gasp! – telephone to find out what was going on.)
What we need in our work communication is not more professional politeness or less formal, chat-based messaging applications like Slack. We need honesty. The problem is that we’ve conditioned ourselves to see honesty as self-indulgent or disrespectful. I’d argue the opposite is true. Honesty, even if it’s a bit more inconvenient for all parties in the moment, pays dividends later. It builds trust. When my partner Anne Helen Petersen and I were interviewing people for our forthcoming book on remote work, a frequent lament from both middle managers and workers was that they didn’t feel like they knew how to succeed in their jobs; that they were guessing what their superiors and coworkers wanted and, even when they asked, they didn’t quite trust the responses they got back.
