This workaround will take care of auto-reply messages for phone calls and messages to the iPhone. There are a lot of users using iCloud emails on iPhone and Mac. You can set a vacation auto-reply on the iCloud email account. Let’s see how to set automatic vacation messages on iCloud email.
But what if you’re only taking off one day? Sometimes, it might seem silly to bother with an out-of-office for such a short amount of time–especially if it’s a day that a lot of other people are taking off (such as a national holiday). If people do need you to get back to them urgently, they’ll think they’re being ignored. (Even if you define “urgently” differently.) And if there’s a chance of an emergency landing in your inbox, it’ll be that much harder for you to unplug because you’ll just keep “checking in.”

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.
Thank you again for being the best team one could ask for. Your energy and persistence has driven our company to new heights, and we greatly appreciate it.
