My OOO auto reply is fairly detailed. I have links to information for products I work with, an alternate point of contact for people to approach, etc. It’s really a CYA thing. What irks me about some OOO auto replies is when the person who is out has an alternate point of contact who is also out. Both are obvious planned absences, and both people are on the same team. Don’t they talk to one another about vacation??
There’s a department at my workplace where this is common practice too. My old department worked with clients in similar ways, and I was half expecting we’d also be required to do it, but luckily that never happened. Further proof that, at this (generally progressive, flexible-working) company, your actual work-life balance heavily depends who manages you.

This is true! The nuclear option also helps the recently returned vacationer understand what is a priority and what isn’t. But, as boyd wrote, “if you just turn off your email with no warning, you're bound to piss off your friends, family, colleagues, and clients.” The blog post offers some helpful steps to make a clean break feasible — they include communicating with colleagues about the sabbatical long in advance, managing expectations of those who rely on you, creating a backdoor for true emergencies, and then, right before going away, reminding everyone about the sabbatical once again.
I am currently out of the store on holidays.We will get back to work on (insert date). If there is something urgent, you can inform me by sending me an email me with the “URGENT” reference in its title and I’ll get back to you as soon as I can.
