I used to work with someone who had a message telling people she only checked her email twice a day. You pretty much needed to call her if you needed anything outside of those times. (She worked in a remote office.) I think she had read one of those books on efficiency that recommended scheduled email time. But there were problems with this: 4. My department often had to email attachments or text to illustrate our questions/concerns. And we were on deadlines. Reading a page of text over the phone was not an efficient use of anyone’s time 5. She did outreach & was often out of the office on site visits, trainings, or travel to these places, but never ever set her OOO for these, because she was “working.” However, she was effectively not available to read emails from other staff until after hours on those days.
Q. Will students who stay on campus during winter break be impacted by this change?

My project is entirely phone based and we don’t have voicemail, either for the project line or individual staff lines. We used to, but we found we spent so much time returning voicemails and getting people’s voicemails that it led to us missing calls and going in an infinite loop.
One thing that happens when you regularly send a newsletter out to tens of thousands of people is that you see a lot of automatic Out Of Office (OOO) email responses. The most common one I receive goes something like this: Hi, I’m out of the office until __ and may be slow to respond to email. If it’s an emergency, you can reach me at __ or please contact __. Thanks!
