It doesn’t say you have to grovel to get what you need. It says you have to ask again when they are in the office to get what you need, which is perfectly reasonable.
Yeah, it’s very strange. I understood changing voicemails to explain that the line can’t actually be answered, but someone is checking the messages and will respond (though that was also only an issue for the first few months), but they had no reason to even mention it for email. I started my job 3 months into lockdown, and by that point, procedures were in place to pretty much allow us to operate normally, albeit with a lot more done electronically than before.

In an instant, you feel a weight lifted from your shoulders, and a choir of angels sing Paul Kelly’s How to Make Gravy around you as you skip out of the office. You gaze upon the masses of workers on the tram, smugly wondering if their out-of-office responses are on yet.
A. Nearly all offices will be closed on Main Campus during winter break; therefore, each department should ensure their telephone messages and out-of-office email replies reflect that their office is closed but resuming normal business hours after New Year's Day. They may also want to note their winter break closure on their webpage.
