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.

A. You should not. Office access will be restricted and operations limited to help reduce utility costs and other related expenses. Unless you are pre-approved by your department leadership to be on campus because your work cannot be interrupted by winter break – for instance, because you have research that would be adversely impacted – you should not be on campus during winter break. This break was established to promote health and well-being, so please take advantage of it.
When I was in university I set my voicemail to, “Hi, you’ve reached Krabby. I’m unable to come to the phone right now, but please DON’T leave me a message. They cost me like, 50 cents each. Mom, this is mostly for you because everyone else knows to text me instead like a normal human being.”
