In the time before your vacation, remind all of the co-workers on your team that you will be gone for the specific dates while also making sure to note your vacation on all internal company calendars. People are busy and can forget things, especially if those things are not happening regularly. You might have shared that you will be gone two months ago, but it’s something your colleagues may have forgotten. So, don’t neglect to remind everyone, because there might be some problems if that happens. Miscommunication is something that can be easily avoided, as in this specific case.
My voicemail is set up to forward to my email. I did this years ago, way before the Late Unpleasantness. And it’s perfect for working remotely. (I have trained my students to use email. My colleagues hate voicemail too, so we use email and gchat. Or walk down the hall when we’re live and in person)

If you need immediate assistance before then, you may reach me on my mobile – (Mobile Number).
There’s a grim, apologetic vibe to these messages — I’m sorry I’m taking time for myself but I’ll try to check in on occasion! They’re a vivid reflection of a work culture that valorizes constant productivity and the near-total overlap of work and life. But they’re also do a terrible job of what they’re intended to do, e.g., set realistic expectations for both sender and recipient. A vague OOO message traps both parties in an uncomfortable liminal space where both productivity and rest go to die. The original sender is left unsure if they’ll be getting a timely response or a whether the email will go ignored for a time or forever. The original recipient has taken what is a rock solid excuse (time off) and cheapened it, offering a backdoor for email guilt to creep in.
